Abstract

The purpose of this thesis is to develop a theoretical method to estimate the optical properties and response of a homogenous, apposition microlens array. While other similar studies of microlens arrays have been performed, none were found to determine the total field of view, overlap in the field of view nor the estimated maximum resolution when using a broadband illumination source based on system parameters and spectral distribution of the input source. The necessary elements of optical theory and equations required for the derivation of the field of view parameters and broadband resolution are presented, including all the assumptions and constraints that were applied. The mathematical simulation model was implemented in MatLab and the simulated results are compared with experimental ones. Both results are shown to be accurate to within an acceptable factor. Finally, all MatLab code written for this thesis is included as attached m-files.
