摘要

A computer-generated hologram consisting of N × N resolution cells produces a reconstructed image consisting of N × N sampling points. Since the width of the primary peaks in the point-spread function is twice the pitch of the sampling points, the intensity at intermediate points between the sampling points depends on the interference between the sampling points. Carefully controlling the complex amplitudes of the sampling points makes it possible to control the intensity not only at the sampling points but also at the intermediate points; the intensity of the reconstructed image can be controlled at 2N × 2N points. Preliminary experiments demonstrating the generation of high-density intensity patterns were performed.
