Abstract

In lens-less projection the illuminating wavefront must be modified, so that after propagation on a certain distance it would form an image on the screen. Formed images will be displayed with frame rate minimum 20 fps in case of animated movie. Thus, the speed of computing is extremely important. Computing might be performed by central processing unit (CPU) or graphics processing unit (GPU). Reaching a compromise between computational complexity (as well as the time of computing) and quality of obtained image is needed. This leads to a need to a proper iteration number of the algorithm, its parameters and size of computing matrices.
