Microcomputer Simulation of a Fourier Approach to Optical Wave Propagation

摘要

This thesis uses spatial impulse response theory adapted from continuous-waveFourier diffraction theory as the basis for a microcomputer program to model pulsed optical wave propagation. Programs to generate uniform circular and uniform square excitation functions are included, along with examples of the spatial impulse response for each. Additionally, two new excitation functions with circular Gaussian and circular Bessel spatial distributions are modelled for use in future research. All programs have been written using the MATLAB software package. This effort provides a means to analyze the transient optical wave propagation a spatially filtered optical source.
