Closed-loop phase-shifting interferometry with a laser diode

Not Accessible

Your library or personal account may give you access

Abstract

A closed-loop phase-shifting Fizeau-type interferometer at λ=633 nm was constructed with the direct frequency modulation of laser diodes. The interferometer is servo controlled fully in the phase domain where optical phases are detected by a two-frequency optical heterodyne method. Stepwise phase shifting was accomplished with good stabilization against external disturbances (vibration, air flow, etc.) and laser frequency fluctuations.
