WebMar 10, 2024 · In mere milliseconds, tensor holography can craft holograms from images with depth information — which is provided by typical computer-generated images and can be calculated from a multicamera setup or LiDAR sensor (both are standard on some new smartphones). This advance paves the way for real-time 3D holography. WebComputer Generated Holograms. First a image was taken of an object (me). The image background was removed and whitespace added around the object to obtain higher transmission. Remember this was one of the requirements to ignore one of the terms. Then the image was propagated to the optimum z using the idl routine.
