ABSTRACT:
An atomic or molecular beam detector is disclosed wherein the beam to be detected is coupled through a chopper to form a spatially modulated beam which is then directed at the pressure sensitive surface of a small sensitive microphone. The electrical output signal of this microphone is coupled to a phase-sensitive detector in order to detect the energy that is present in the signal at the frequency corresponding to the chopping rate. In the specific embodiment disclosed, a light beam is also coupled through the chopper in order to develop a second electrical signal which is mixed with the electrical output of the microphone and then coupled through a low pass filter to provide a DC signal when the atomic or molecular beam is present.
