Laser event recorder

Abstract

The primary objective of this effort is to develop a low-cost, self-powered, and compact laser event recorder and warning sensor for the measurement of laser events. The target requirements are to measure the wavelength, irradiance, pulse length, pulse repetition frequency, duration and scenery image for each event and save the information in a time and location stamped downloadable file. The sensor design is based on a diffraction grating, low-cost optics, CCD array technology, photodiodes, integral global positioning sensor, and signal processing electronics. The sensor has applications in laser safety, video surveillance and pattern recognition.
