Abstract:
A multi-channel optical receiver system comprising:means for modulating a substantially coherent light beam with an input RF signal;means for channelizing said RF modulated light beam into an array of channels, each channel containing a Fourier transform replica of the RF modulated light beam;means for combining said array of channels with a local oscillator light beam and for dividing said combined array into a first combined array and a second combined array;first and second programmable filter means for selectively passing signals in each channel of said first and second combined arrays respectively;first and second detector means for respectively converting the signals passed by said first and second programmable filter means into first and second electrical output signal arrays; andcontrol means for programming said first and second filter means in response to said first electrical output signal array to selectively pass signals having selected characteristics.
