Advanced Hit Detection Systems

FreEnt Technologies, Inc. (FreEnt) and Johns Hopkins Universitys Applied Physics Laboratory (APL) are proposing a multiple-hit detection sensor called the Optical Lethality Measurement System (OLMS). This system is based on the Planar Optical Penetration Sensor (POPS) technology (originally developed and patented by APL) and prior art associated with the Blast Initiation Detector (BID). The BID is a high-speed optical system that detects the time of initiation of a proximate warhead burst in the vicinity of the target vehicle. During the first phase of the POPS system development, APL demonstrated the feasibility of detecting multiple hit-detections from a single planar POPS detector. During this effort the POPS technology will be matured providing an initial pathway for the OLMS to be used in flight tests to include the fabrication of two OLMS hardware items, an Engineering Development Model (EDM) and a Flight Hardware Model (FHM).
