Abstract

In this investigation, the quasimonochromatic condition is not assumed, and the spectral-density function of the radiation depends on frequency as well as on positions. We discuss various models for the impulse-response function of the optical system, and examine the results in temporal-frequency space. We approximate the integration by employing the method of steepest descent. An explicit relation of the mutual coherence function and the spectral-density function of the source is established with some correction factors that differ from the results of the quasimonochromatic approximation.
