Double Pinhole Spatial Phase Correlator Apparatus.
Abstract
A random wavefront is incident on an aperture plate with a double pinhole of variable separation that is followed by Fourier transforming optics which focusess an intensity profile on a detector array. The detector array is located in the Fourier transform plane of the Fourier transform lens. The time average of the intensity as a function of hole separation yields the root mean square phase and the phase correlation function of the applied wavefront. (Author)
