    2D - 3D - 4D
    (Andersen M Studio, 2012) Richardson, Martin
    Apart from being a security device holography has the potential to become the ultimate 3-D format within the next few decades as the holographic image can be called a true replica indistinguishable from reality. But there is much more to holographic imagery than mere replication. Holography had its beginnings in 1948. Denis Gabor, a Hungarian-born physicist working for the electrical company British Thompson Huston based in Rugby, UK, who was atempting to improve the resolution of electron microscope images and hit upon the idea of recording the actual radiated wavefront emanating from the object. As a beam of electrons could not at the time be made coherent he used green-filtered light light from a mercury vapour lamp. In a seminal paper describing his findings (Gabor 1949) he explained how light of a single frequency carried all the information describing the object contained in the light wavefront and soon after named his invention holography, the word holography comes from the Greek words ὅλος (hólos; "whole") and γραφή (grafē; "writing" or "drawing"). This, he argued, could be recorded on a photographic emulsion. He succeeded in achieving this after a fashion, though his mercury lamp produced a band of wavelengths nowhere near as narrow as he would have desired. As a result of this large bandwidth his earliest images had to be very small two-dimensional transparencies no larger than a pinhead, and even these were blurred, and distorted by an unwanted complementary image directly in front. But although his experiment was crude and unconvincing his theory was sound, and he was eventually to receive the Nobel Prize for Physics in 1971 for his ingenuity, though others had needed to find methods of making his ideas workable. Today holograms appear everywhere, on bank cards, passes and any document that needs security protection. Holography also finds applications in the decorative trade, and in engineering, where it is used in nondestructive testing in the form of holographic interferometry.

    THE ANDROID HEART
    (Compass-Publishing, 2019-12-19) Richardson, Martin
    When technological development surpasses its original intention, making the original definition redundant, the need to adapt, or transcend, definition is an imperative. For example, “hologram” is defined in many dictionaries as a three-dimensional image of a photographic surface. However, it’s etymology, as used in imaging processing for three-dimensional displays, often loses its scientific definition because descriptive language falls short of the technological advances being made.

    As The Two Roads Diverged I Took The One Less Travelled, And That Has Made All The Difference
    (University of Aveiro, Portugal, 2018-06-19) Richardson, Martin
    Is it possible that holograms will one day communicate with us in real-time using artificial intelligence (AI) to shape reality itself? With Microsoft HOLO-lens ™promising tomorrow’s world today and the future-trends of ‘True Colour’ holograms and beyond, the continuing developments of photonics promise to satisfy our innate need for the mythical, the unobtainable, the impossible. The author suggests that holographic imaging draws upon our evolutionary DNA to drive the science behind the development of photonic technology and wave front reconstruction. A passionate Affair de Coeur (affair of the heart) between Art and Science, without which its evolution would not be possible. The paper offers thoughts regarding the impact of Artificial Intelligence (AI) and holography. As the science fiction novelist William Gibson famously observed “The future is already here – it’s just not very evenly distributed”, a truism when placed within the context of holography. (The title of this paper is paraphrased from the poem ‘The Road Not Taken’ by the American poet Robert Frost. It uses this metaphor to illustrate some thoughts, reflections and contemplations on AI and colour holography.)

    Crystal beginnings II: The Mind Map of Holography
    (SPIE, 2008) Richardson, Martin
    At the SPIE Photonics West Conference held in San Jose in January 2006 I presented the first part of this paper outlining a concept for three-dimensional mind maps. With the help of a detailed questionnaire completed by members of the audience, we sort to gain detailed insight as to the future of holography, after all if you want to ask a question ask the experts who’s answers are based upon rational judgment rather than merely guessing. This paper is the result of that questionnaire and has been distilled with graphics for simplification. The paper also contains an appendix of twenty-two applications noted in the questionnaire by those expert holographers kind enough to participate in that Delphi.

    CυBE: Coherent υ Beam Educator
    (S.P.I.E, 2017-03-03) Richardson, Martin; Sureshkumar, Vivian Amos
    Holography has advanced rapidly over the years due to technical melioration in the field of optics. Three-dimensional imaging has gained importance to upgrade the existing imaging and display system. Holography has become one of the branches of optics gaining significant importance with a vast number of technical and industrial applications. When we address holography the first thing that comes to mind is projecting a three dimensional object on thin air. The word holography has always been confused between peppers ghost effect. The famous English phrase “A picture is worth a thousand words”, means a complex idea can be conveyed by a single picture. The basic principle of holography sounds complex with all its technical terms. This paper aims to explain the concept of the CυBE: Coherent υ Beam Educator that contains a transmission hologram illuminated with a laser diode. This paper summarizes the construction details of the CυBE and the optical setup to record the transmission hologram. It also briefs the circuit connections for the laser diode that’s works with an aid of a push button. When viewer presses the push button the original scene is reconstructed. It provides details regarding the angle of reference beam at recording and how the reference beam is compensated at reconstruction. Also this paper highlights how the magnification of the recorded image is affected with respect to the path length of the laser diode inside the box during reconstruction of the recorded hologram. © (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    Holograms: Principles and Techniques
    (Wiley & Sons, 2017-02) Richardson, Martin; Wiltshire, J.
    With the legacy of the inventions of Lippmann, Gabor et al, we are lucky enough to have been the generation who have experienced the dawn of the age of holography first hand. Still, when we think of holograms, we think of the future, a place full of wondrous inventions. A place where driverless cars defy gravity, civilization is established on Mars, or cities are built under earth’s oceans. And then, of course, holographic images that materialize in thin air and communicate with each other using artificial intelligence, indistinguishable from human consciousness. Such is the legacy of science fiction. In reality, this vision of the future may fall far beyond the laws of physics, but nevertheless there are some truly astounding developments taking place right now in the field of holography right now. I know, because as a research professor at De Montfort University, I’ve had the privilege of experiencing some of the world’s most incredible three-dimensional holograms and it’s a glimpse into a future I want to share with you!

    Holographic data visualization: using synthetic full-parallax holography to share information
    (SPIEProceedings@SPIE.org, 2017-03-15) Richardson, Martin; Dalenius, Tove Noorjahaan; Rees, S. J.
    This investigation explores representing information through data visualization using the medium holography. It is an exploration from the perspective of a creative practitioner deploying a transdisciplinary approach. The task of visualizing and making use of data and “big data” has been the focus of a large number of research projects during the opening of this century. As the amount of data that can be gathered has increased in a short time our ability to comprehend and get meaning out of the numbers has been brought into attention. This project is looking at the possibility of employing threedimensional imaging using holography to visualize data and additional information. To explore the viability of the concept, this project has set out to transform the visualization of calculated energy and fluid flow data to a holographic medium. A Computational Fluid Dynamics (CFD) model of flow around a vehicle, and a model of Solar irradiation on a building were chosen to investigate the process. As no pre-existing software is available to directly transform the data into a compatible format the team worked collaboratively and transdisciplinary in order to achieve an accurate conversion from the format of the calculation and visualization tools to a configuration suitable for synthetic holography production. The project also investigates ideas for layout and design suitable for holographic visualization of energy data. Two completed holograms will be presented. Future possibilities for developing the concept of Holographic Data Visualization are briefly deliberated upon. © (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    Holographic Space: Presence and Absence in Time
    (S.P.I.E, 2017-03-03) Richardson, Martin; Chang, Yin-Ren
    In terms of contemporary art, time-based media generally refers to artworks that have duration as a dimension and unfold to the viewer over time, that could be a video, slide, film, computer-based technologies or audio. As part of this category, holography pushes this visual-oriented narrative a step further, which brings a real 3D image to invite and allow audiences revisiting the scene of the past, at the moment of recording in space and time. Audiences could also experience the kinetic holographic aesthetics through constantly moving the viewing point or illumination source, which creates dynamic visual effects. In other words, when the audience and hologram remain still, the holographic image can only be perceived statically. This unique form of expression is not created by virtual simulation; the principal of wavefront reconstruction process made holographic art exceptional from other time-based media. This project integrates 3D printing technology to explore the nature of material aesthetics, transiting between material world and holographic space. In addition, this series of creation also reveals the unique temporal quality of a hologram’s presence and absence, an ambiguous relationship existing in this media. © (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
