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).
