Heterodyne based optical spectrum analysis with reduced data acquisition requirement

Heterodyne based optical spectrum analysis (OSA) involves mixing an input signal (402) with a swept local oscillator signal (406) to generate a heterodyne beat signal and then stretching the heterodyne beat signal before the signal is sampled. A system for optical spectrum analysis includes a local...
