OPTRA's Laser Event Recorder (LER) wins Aviation Week's Product Breakthrough Award! November 15, 2004 This low-cost, light-weight, laser event recorder has been designed to capture and record laser exposures. The battery powered, self-contained sensor is rugged enougt for the most demanding applications (e.g. aricraft or vehicle mounted) yet small and light enough to be worn by an individual. The laser event recorder has a large field of view and is designed to measure laser wavelength, radiant exposure level, pulse duration, repetition rate, and is able to discriminate against natural and man-made light sources. When the laser event recorder detects laser radiation, it provides a visual indication of whether the exposure is eye safe or hazardous (as defined by ANSI Z136.1 2001) and captures a digital image of the scene containing the laser and stores all the data in a time-stamped, downloadable file. The laser event recorder can operate unattended for up to six hours. Although designed around specific Navy requirements, the versatility of the design will allow immediate use by other services, agencies and security groups charged with the protection of civilian assets (commercial aircraft, large commercial buildings, nuclear power plants, etc.) Monitoring of unintentional illumination of spectators at events involving laser light shows is yet another potential application of the laser event recorder.
