Laser Exposure Measurement Device

The widespread use and deployment of laser systems has led to the need for laser exposure measurement systems that operate over wide spectral range and provide sufficient dynamic range to measure exposure relative to maximum permissible exposure (MPE) limits and establish normal hazard zones. OPTRA, Inc. proposes a solution based on the complementary combination of CMOS readout integrated circuitry and diffractive optics to directly measure the laser characteristics and evaluate the exposure with respect to MPE limits established by the ANSI Z136.1 standard. In the Phase I R&D effort, OPTRA, Inc. will develop optical and electronics models, perform tradeoff analyses, predict system performance, and perform a laboratory demonstration to establish the feasibility of the proposed approach to meet the DHS requirements.
