SLM Simulation and MonteCarlo Path Tracing for Computer-Generated Holograms

Abstract

Computer holography is a growing research field that must pay attention to two main issues concerning computing effort: the visualization of a 3D virtual scene with photo-realistic quality and the bottleneck related to hologram digitizalition and visualization limits. This work shows a computational approach based on a Monte Carlo path-tracing algorithm, which accounts for both geometrical and physical phenomena involved in hologram generation, and, therefore, makes a feasible estimation of computing time costs. As these holograms also require yet unavailable visualization devices, their behavior needs to be simulated by computer techniques.

Partial Monte Carlo sampling for computer generated holograms

“…The higher the rate, the more faithfully movement is perceived. A detailed cost estimation analysis for CGH calculations are compiled in Reference 11. The main problem to achieve the desired results is the calculation time, which depends directly on the number of rays used to calculate the scene.…”
