Paper Abstract

It has been demonstrated in a laboratory experiment that a mode-locked laser can be used as a local oscillator (LO) in a heterodyne ranging system to sample or bandwidth com-press the received signal. The bandwidth compression depends on the difference in the intermode frequency between the LO laser and the transmitter laser. Bandwidth compression of over 500 times was demonstrated, i.e., a 1.5 GHz He-Ne laser transmitter signal was reduced to 3 MHz upon detection. Since the mixing occurs on the surface of the detector only a narrow bandpass receiver that passes the compressed bandwidth is necessary to obtain ranging equivalent to that obtained by a wide bandwidth receiver that passes the full transmitter bandwidth
