Abstract

A new approach to obtain simultaneous differential phase and intensity scans from an optical profilometer/microscope is described. The proposed configuration achieves these objectives by multiplexing two interferometers in time. Optimum differential intensity and phase response are achieved without the compromise associated with previous systems.
