    Full-parallax digital holography, anatomy, and art
    (SPIE, 2023-03-08) Dalenius, Tove Noorjahaan
    Working in the full-parallax digital format with the CHIMERA holography technology, which offers a 250 micrometre hogel size ensuring a clear image, this project explores anatomical imaging from an artist’s perspective. A completed hologram visualises anatomical MRI scans, adapted from a 3D printable model of the Bulbo-clitoral organ, building on studies in urology. A collage approach has been taken to include structural detail and creative vision. The work takes advantage of the available colour representation offered through continuous wave RGB laser technology. Transparent modelling options are explored. A Practice-Based Research method has been adopted to investigate creative possibilities in display holography.

    Holographic data visualization: using synthetic full-parallax holography to share information
    (SPIE, 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).

    Revealing Emergence
    (Intellect, 2025-01-23) Dalenius, Tove Noorjahaan
    The artist and technology researcher Tove Noorjahaan Dalenius shares the journey of discovery, creative practice, technological research and academic dissemination, as well as face-to-face exhibition of the direct-write digital hologram Emergence, which visualizes the full extent of the clitoris in its anatomical setting. The intent is to invite readers to consider the entire endeavour through an organic and integrated approach. The project was built through a multidisciplinary process, using a practice-based research method. Through active collaboration and using collage visual methods, Dalenius created a well-researched transplane work of art which engaged audiences. The description of the exploration includes both facts and figures and some personal reflections to situate the journey. This article covers the inception of the project through to the exhibition of the artwork, a time span of fifteen years. The research concerning the anatomy of the clitoris by urologist Helen O’Connell and a visualization model by researcher and anti-sexism activist Odile Fillod are introduced. The reader is familiarized with the creative and technical medium of direct-write digital holography (DWDH). The work of art Emergence is revealed and details of the work are discussed. Finally, Dalenius describes displaying the work at the SPIE Photonics West conference, and The Women’s Building community centre in San Francisco, United States. Dalenius also brings the reader along to the Women in Tech 2023 conference in Stockholm and shares how Emergence became cover news for the feminist magazine Feministiskt Perspektiv (FemPers). The article is illustrated by ample images. By mixing innovative research in both the fields of anatomy and imaging technology, the artist/researcher/technologist has been able to create both beautiful and informative piece of art which engages the viewer. Through interaction with global audiences in different communities and settings, the work and the artist have informed, entertained and raised further questions and curiosity about anatomy, holography and societal issues.

    The use of full-parallax colour digital holography as an artistic medium
    (De Montfort University, 2023-11) Dalenius, Tove Noorjahaan
    This thesis maintains that full-parallax direct-write digital holography (DWDH), or in contemporary shorthand ‘digital holography’, can be successfully used as an artistic medium, as evidenced by my full-parallax, full colour, hologram, Emergence. This hologram visualises the complete structure of the Bulbo-clitoral organ within the body. It was created using Ultimate Holography’s Chimera technology with 250 micrometre hogels and has outstanding colour. It is a cutting-edge work, advancing the field in the context of contemporary artworks, and it paves the way for future research and practice opportunities. The practice-based research leading up to and including the production of Emergence includes examples of experimentation and collaboration. It provides original insights into the practice of creation in the three-dimensional medium of holography, with multi-dimensional interdisciplinary applications in art, culture, anatomy, and science. Taken together, the four new studies presented in the thesis build a background of exploration of the medium of digital holography, in resonance with the various fields of inspiration for the envisioned artworks. The studies explore ideas and give insight into practical workflows, and the thesis identifies and discusses both the opportunities and barriers to using the medium for data visualisation, and to create artworks using elements of data visualisation. Each study comes from a distinct idea with its own motivation and backstory. By detailing an individual artistic journey, the thesis shares the knowledge gained for the benefit of future artists, designers, and researchers in the field. It is intended to make digital holography practice more accessible for future users. The research assists both creative practice and technological development in digital holography both by creating a piece of new work at the frontier of the possible and through detailed disclosure of the processes used to achieve it.
