METHOD FOR SENSING ACOUSTIC ENERGY

A method for sensing acoustic energy as the energy passes from a more dense to a less dense medium while compensating for energy level loses that may have occurred along the acoustic path of the acoustic energy. The method may be used to replace a multi-sensor system for detecting acoustic energy. T...

Zusammenfassung:	A method for sensing acoustic energy as the energy passes from a more dense to a less dense medium while compensating for energy level loses that may have occurred along the acoustic path of the acoustic energy. The method may be used to replace a multi-sensor system for detecting acoustic energy. The method includes permitting the acoustic energy to progress from a first transmitting medium to a second transmitting medium, the first transmitting medium being more dense than the second transmitting medium and the first medium being contiguous with the second medium along a predetermined interface; disposing an optical sensor in the second medium so that at least a portion of the acoustic energy imposes a modulation proportional to the frequency components of the acoustic energy on a sampling light emitted by the optical sensor; and detecting at least a portion of the sampling light having modulation in response to the portion of the acoustic energy.
