ABSTRACT:
This Passive Long Range Acoustical Sensor relates to means of sensing acoustical sources and signals, including multi-channel acoustical signals, such as various types of sounds, vibrations, flutter, turbulence, and the like, and at long distances through a natural optical channel, without the use of a laser or other artificial illuminating means. A modified multi-channel embodiment of the Passive Long Range Acoustical Sensor may use a combination of natural optical channels and active illumination means, such as laser or other artificial illuminating means, of producing additional optical channels.
