High-dynamic-range measurement of the two-point field correlation function by carrier-encoded spatial shearing interferometry.
We present a new technique for the direct measurement of the two-point field correlation function of a monochromatic light source based on carrier-encoded lateral shearing interferometry. The technique provides a higher dynamic range and a significant reduction of the amount of data compared with previously demonstrated methods. We demonstrate the measurement of coherent and partially coherent sources.
