Optical signal processing device

摘要

An optical system including a radio frequency signal input; a chirp signal input; a source for emitting a beam of radiation; a first acousto-optical modulator disposed in the path of the beam and functioning to modulate the beam with the radio frequency signal to produce a first modulated beam; a second acousto-optical modulator disposed in the path of the first modulated beam to modulate the beam with the chirp signal to produce a third modulated beam; and a single detector disposed in the path of the third modulated beam.
