Measuring the spatial coherence from an extended quasi-monochromatic source by double-exposure speckle interferometry.
Double-exposure speckle interferometry is used to measure the degree of spatial coherence from an extended quasi-monochromatic source. The method closely follows the theory of spatial coherence and allows easy interpretation of results; it can be implemented with a compact interferometer based on laser speckle patterns.
