Improved Laser Event Recorder (I-LER)

Physical Sciences Inc. will develop an Improved Laser Event Recorder (I-LER) that is a plug-in accessory to a smart phone. The proposed design moves several of the largest and costliest items in the original LER, including the power supply, GPS, context camera and microprocessor, into a single mass-produced item. Performance improvements will include an updated discrimination algorithm to reduce false alarm rate and an extended spectral range of 400-2000 nm.  A system model will be generated and Phase I breadboard developed to establish feasibility and validate the system model.  The breadboard will be tethered via USB to a standard commercially-available smartphone on which all processing will be demonstrated.  Improved algorithms will be developed and validated on simulated and breadboard data.  Requirements and a conceptual design will be generated for a prototype I-LER to be developed in Phase II.
