Modelisation and Conception of a Michelson Interferometer based on Digital Micromirrors

Abstract

This research explores the design and simulation of a modified Michelson interferometer aimed at improving Optical Coherence Tomography (OCT) through the integration of digital micromirrors. By replacing the static reference mirror with independently controlled micromirrors, the system enables parallel A-scan acquisition, significantly increasing imaging speed. Using COMSOL Multiphysics, we simulated single-beam and multi-beam configurations to analyze the impact of optical path variation on interference patterns and depth resolution.
