Abstract

Blackbody radiation is a gaussian stochastic process and a knowledge of the moments of its energy spectrum (Planck radiation law) is sufficient to enable the determination of the expected number of zero crossings of the electric field vector as well as the expected number of peaks and expected number of maxima. Explicit formulas are presented for these quantities in terms of the Einstein function and transport integrals. In addition, the spectrum of the intensity fluctuations is obtained and similar calculations performed. Typical numerical results are shown.
