    摘要: Some embodiments relate to an optical microphone according to an example embodiment. The optical microphone includes a semiconducting laser. The semiconducting laser includes a p-n junction within a cavity. The optical microphone further includes an acoustic membrane that receives coherent light emitted from the semiconducting laser and directs reflected light back toward the semiconducting laser. During operation of the optical microphone, the acoustic membrane flexes in response to pressure waves. The phase of the reflected light is dependent upon a distance of the acoustic membrane from the semiconducting laser.

    摘要: An apparatus for remote detection or neutralization of an explosively formed penetrator device. A LIDAR or LADAR unit may be used in conjunction with a RADAR unit to both detect the presence of an EFP and neutralize the EFP having an associated passive infrared sensor. The LIDAR unit's wavelength is selected to approximate the signature from the intended EFP target which then causes the safe remote detonation of the EFP. The detected EFP signature may be compared with known signatures and presented to a user via a display terminal. The display terminal may also present associated terrain or GPS data.
