Abstract
This paper discussed the principle of amplitude modulation and coherent detection, then designed freedom homodyne coherent receiver system, included optical schematic design and the receiver signal acquisition & processing. Through NI data acquisition card acquire signal and LabVIEW graphical program software accomplish signal processing. The detection and collection methods can be applied to the phase and polarization of the demodulation processing.
