Abstract

A family of raster mappings for the optical spectrum analysis of broadband signals is presented. This family contains as one member the conventionally used falling raster of C. E. Thomas. An analytical model, appropriate for space-integrating coherent optical spectrum analyzers, is given for the raster input and the Fourier plane distribution. The family of raster mappings and its Fourier transform is shown to be a continuous domain analog of the I. J. Good fast Fourier transform algorithm.
