摘要： The present disclosure relates to a velocity interferometer. The interferometer described herein, comprises of two optical cells, one partially containing a liquid. The light entering the interferometer is amplitude split and made to propagate through the two cells in such a way that the apparent path lengths of the beams are equal, thereby fulfilling the condition necessary for obtaining single wide fringe in the interference pattern of the two beams. However, due to difference in the physical path traversed by the two beams, a finite delay time exists between them. The two beams, after reflection from end-mirrors or cube corner prisms in the two cells are recombined to form interference fringe patterns on active areas of multiple detectors. Doppler shifted light resulting from reflection of light from a moving projectile generate fringe shifts on the detector planes thereby producing voltage signals proportional to instantaneous velocity of fast moving projectile. The voltage signals are recorded with multi-channel digital oscilloscope and processed in a processor/controller of a computing unit to obtain velocity time history of the projectile. Controlled motion of the cube corner reflectors placed at the ends of two cells using stepper motors and piezoelectric actuators ensures that the time delay between the interfering beams is controlled accurately thereby changing the sensitivity range and time resolution of the velocity measurements.

摘要： A system and method to detect an object buried beneath the seabed are described. The system includes a moving platform, a low frequency signal source coupled to the platform to transmit a low frequency signal to an area of the seabed, and a laser Doppler vibrometer (LDV) coupled to the platform to transmit a plurality of transmission beams to the area of the seabed at a respective plurality of angles at each position of a plurality of positions of the platform over the area. The LDV includes a plurality of receivers that receive a respective plurality of reflection beams resulting from the plurality of transmission beams. A processor develops a three-dimensional image that indicates the object, the processor determining a reflection value at each point of the three-dimensional image as a coherent combination of reflection from the point contributing to each of the plurality of reflection beams.

摘要： In an aspect, a processing apparatus receives detection signaling indicating a field incursion in a detection field of a LIDAR device mounted to a marine vessel and oriented to detect objects within a free space alongside the marine vessel. The processing apparatus applies plausibility testing to the field incursion, including determining whether parameters derived from the detection signaling are characteristic of a human body falling from the marine vessel through the detection field. The processing apparatus outputs signaling indicating a person overboard event to an alarm or control system onboard the marine vessel, in response to the field incursion passing the plausibility testing.

摘要： Systems, devices, and methods for proximity-based eye tracking are described. A proximity sensor positioned near the eye monitors the distance to the eye, which varies depending on the position of the corneal bulge. The corneal bulge protrudes outward from the surface of the eye and so, all other things being equal, a static proximity sensor detects a shorter distance to the eye when the cornea is directed towards the proximity sensor and a longer distance to the eye when the cornea is directed away from the proximity sensor. Optical proximity sensors that operate with infrared light are used as a non-limiting example of proximity sensors. Multiple proximity sensors may be used and processed simultaneously in order to provide a more accurate/precise determination of the gaze direction of the user. Implementations in which proximity-based eye trackers are incorporated into wearable heads-up displays are described.
