ABSTRACT:
A bathyphotometer system is described for detecting photoluminescent signals excited by a grid disposed in a marine vehicle. The system uses photodiodes to convert the optical signals into electrical signals which are sampled, integrated and coupled to output terminals for transmission to a surface host vehicle. In one embodiment the signals are digitized and encoded as FSK tones for transmission to the surface host vehicle.
