PSI’s Improved Laser Event Recorder

Physical Sciences Inc. (PSI) has been awarded a research program from the U.S. Naval Air Warfare Center to develop an Improved Laser Event Recorder (I-LER) that is a plug-in accessory to a smart phone.

The I-LER will build upon the proven original LER concept exploiting the sparsity of point-source laser events with a novel hyperspectral imaging architecture. PSI’s 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.

The number of laser events reported by military and commercial aircraft continues to rise. This is a concern for both flight safety and pilot health. The I-LER benefits include: immediate information available to pilots to assess the level of threat, real-time data on the nature of laser radiation to assist in evaluation of visual health impact, and forensic data to aid in the identification and apprehension of perpetrators of aircraft lasing events, all at a lower cost and reduced SWAP relative to existing LERs.
