【 摘 要 】

The purpose of this thesis is to develop a theoretical method to estimate the opticalproperties and response of a homogenous, apposition microlens array. While other similarstudies of microlens arrays have been performed, none were found to determine the total field ofview, overlap in the field of view nor the estimated maximum resolution when using a broadbandillumination 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 ofview parameters and broadband resolution are presented, including all the assumptions andconstraints that were applied. The mathematical simulation model was implemented in MatLaband the simulated results are compared with experimental ones. Both results are shown to beaccurate to within an acceptable factor. Finally, all MatLab code written for this thesis isincluded as attached m-files.
