Computational Holography Meets Computer Graphics

Speaker: Dr. Mark Green (FS)

Abstract: Holography is the ultimate display technology since it accurately reproduces all of our 3D visual cues, which isn’t the case with other display technologies. Holography has largely been ignored by the computer graphics community because of its perceived computational expense and the low quality of the images produced by most computational holography algorithms. With massively parallel processors the first problem is going away and a new class of computational holography algorithms that we are developing will hopefully solve the second one.
This presentation covers basic holography and the mathematics and physics behind it. This is followed by a brief description of the holographic display devices that we’ve constructed. The main part of the talk is a discussion of algorithms that can be used to compute holograms along with their computational challenges. This include a brief summary of the two main classes of computational holography algorithms along with a new class of algorithms that we are currently exploring.
