A servo-stabilized wave-front folding type of interferometer has been constructed for spatial coherence measurements. Sinusoidal phase-modulation is imposed on either wave-front of light in the interferometer in order to facilitate signal processing and servo-signal generation as well. The servo-stabilized optical system makes it possible to obtain reliable results as well as calibrate the measured erroneous phases due to imperfections of the optical components.
