Hybrid optoelectronic system for wideband complex-valued Fourier transform measurements.
A hybrid optoelectronic system for Fourier transform measurements of temporal signals is described. The magnitude and phase of the signal transform are system outputs. High resolution spectral analysis operation is accomplished by proper spatially dependent phase corrections equivalent to aperture synthesis. Configurations for 1-D and 2-D input data formats are discussed. The system can process signals with continuous spectral content as well as narrow spectral lines.
