Abstract: The possibility of using temporal analysis to find the relation between chromatic properties of probe radiation and coherent properties of the optical images of rough non-planar objects is substantiated. The analysis is based on the use of the time correlation function and on the study of the speckle pattern contrast in the optical images. The conditions are determined under which the different parts of the optical image of an object are coherent, partially coherent and incoherent, while probe radiation is manifested as monochromatic, quasi-monochromatic, and polychromatic. It is shown that these conditions depend considerably on the object surface shape. The use of the temporal analysis for three-dimensional imaging of an object by its planar images and improving the optical image quality by removing its speckle pattern is illustrated by examples.
