Abstract:
With the help of a folded-wavefront type of interferometer, a sinusoidally phase-modulated wavefront can be superposed in parallel on another nonmodulated inverse wavefront. Spatial coherence is related to the fundamental and second-harmonic components of the modulation frequency included in the resultant intensity.
