Abstract
The dispersion of modulated or time-varying light is analyzed for an arbitrary disperser, general modulation, gaussian and incoherent illumination, and nonideal optical systems. The conditions for quasi-static response are examined in detail, and a stricter condition than that previously published is derived. The practical implications of this condition are discussed. The moments of the intensity distribution are derived for the general case. The analysis is related to specific dispersing elements.
