The Angular Spectrum Method (ASM) is a technique used in optics, particularly in the analysis of wave propagation and diffraction of light. It is based on the principle of representing a wavefront as a superposition of plane waves. This method is widely used in computer science and engineering fields, especially in image processing, optical system design, and simulation of wave propagation in various media.
