Analysis and Implementation of a Direct Phase Unwrapping Method for Displacement Measurement Using Self-Mixing Interferometry

Self-mixing or optical feedback interferometry has been widely used for displacement and velocity measurement applications. For metric information retrieval with <; λ/2 precision, various phase unwrapping methods have been proposed. However, these are computationally heavy and require large numbe...
