How it Works
Reference and test beams travel the common path through the optical system of the interferometer. Our simultaneous phase-shifting common-path Fizeau interferometer is accomplished using ESDI¡¯s revolutionary HyperPhase™ Module (patents pending). The module uses three sub-pixel aligned cameras, which are monolithically bonded together with the beam splitting and polarization optics into a rugged package smaller than two stacked deck of cards. The result is a rigid camera system similar to high-end 3-Chip color cameras with lifetime alignment. The advantage of using three cameras is that each of the interferograms retains the true resolution of the camera.
