ABSTRACT:
A method and apparatus for transmitting beams of electromagnetic energy. A plurality of beams having a first number of frequencies and a number of beams having a second number of frequencies are transmitted. The plurality of beams and the number of beams overlap each other at an area with a pattern of intensities in the area. Difference frequency signals having a number of difference frequencies equal to a difference between the first number of frequencies and the second number of frequencies are monitored. The difference frequency signals are generated by an object having non-linear electrical characteristics in response to receiving the plurality of beams and the number of beams.
