New display technologies capable of reproducing realistic 3D images are now under development. In the near future, it may even be possible to bring the fictional “Holodeck” to reality – creating a truly immersive, glasses-free visual experience. In this segment, you’ll learn about recent developments in these Immersive Displays, including multiplanar, volumetric, wavefront holography and light field. This range of technical approaches can be described through a taxonomy of optical design based on generating either points of light, rays of light or waves of light. These methods each have advantages and disadvantages, so will likely support different applications and use-cases.
