Abstract
An apparatus comprises a transmitter system, a receiver system, and a processor unit. The transmitter system transmits first and second collimated beams having a first and second frequency. The receiver system monitors for a fundamental difference frequency signal having a difference frequency equal to a difference between the first and second frequency and a number of harmonics of the fundamental difference frequency signal. These signals are generated by an object having non-linear electrical characteristics in response to the collimated beams. The processor unit is connected to the transmitter system and the receiver system. The processor unit controls the transmitter and receiver systems to change at least one of the first and second frequencies through a range of frequencies and detect a range of fundamental difference frequency signals and the number of harmonics of the fundamental difference frequency signal in response to transmitting the collimated beams using the range of frequencies.
