Abstract
We describe heterodyne spectrum analyzers that operate with a significantly reduced number of photodetector elements. The technique is to decimate an N-element photodetector array by retaining only every Mth element. We time-share the remaining elements by scanning the spectrum across the decimated array. Each photodetector therefore produces, as a time sequence of samples, the spectral content of the received signal over its associated spatial frequency range.
