Abstract

This thesis utilizes the finite element method (MSC/NASTRAN) to perform an analysis on an optical-mechanical laser scanner used in the imaging industry. A Normal Modes analysis was conducted to determine the real eigenvalues and their associated eigenvectors. The results of the analysis (modal frequencies and modal shapes) were then compared with empirical data measured using a FFT (Fast Fourier Transform) analyzer with modal software (Hewlett Packard 5423A Dynamic Signal Analyzer). The dynamic characteristics of the system optical output beam and optical components were evaluated by simulating the optical components using rigid bar elements. A modal frequency response analysis was performed to determine the motion (amplitude and direction) of the system optical output beam at the focal point of the system.
