Absolute distance measurement using a multi-stage evaluation algorithm on sinusoidally phase-shifting interference signals via laser injection current modulation
Abstract We present a laser interferometric measurement system for absolute distance measurements based on currentmodulated laser diodes in the telecommunications wavelength range. The sensor system described here uses two lasers with slightly different wavelengths in a point-wise measuring interferometer and enables t...
