Piece-wise transition detection algorithm for a self-mixing displacement sensor Download: 1193次
Abstract
A piece-wise transition detection algorithm that performs displacement measurements for self-mixing sensors is developed. The algorithm can correctly detect self-mixing fringes at a low signal-to-noise ratio in the presence of disturbances without filtering. Displacement reconstructions by the phase unwrapping method based on this algorithm are experimentally validated, with laser subject to the moderate feedback regime.
