摘要
A wave-front-folded interferometer composed of a Kosters prism and an image-forming lens provides a good way of measuring the complex degree of spectral coherence. Demonstrative experiments are implemented by incorporation of uncorrelated two-point spectral sources in the primary-source plane; these sources establish a spatially partially coherent wave field over the secondary source plane just in front of the interferometer. The complex degree of spectral coherence of the secondary source is successfully measured after an a priori calibration is made for the interferometer that was constructed.
