Dual Optical Ultrawide Band Laser Eyeware Transmission Field Evaluation Device

To address the U.S. Air Force need for a fully enclosed laser eye protection evaluation device, Physical Optics Corporation (POC) proposes to develop a new high-resolution, high-dynamic-range, self-calibrated, compact, and security protective Dual Optical UltrawideBand Laser Eyeware Transmission (DOUBLET) densitometer. DOUBLET is based on efficient POC ultrawideband transmission holograms and a fully symmetrical, robust, simple, and reliable bulk-optics design with no moving parts, ensuring long-term stability, DOUBLET provides 1.5 nm resolution and 0-5 OD range. It incorporates two sets of independent multispectral channels (for 400-750 nm visible and 750 1400 nm IR ranges) with identical optical components and geometry. The proposed DOUBLET densitometer is sensitive to 0.1 OD, light-efficient, and lightweight. In Phase I POC will demonstrate DOUBLET feasibility with a proof-of-concept device in a laboratory by designing, modeling, and analyzing the performance of its components and main functions: 1000 nm wide optical density measurements, wavelength identification, and self-calibration. In Phase II POC plans to develop an integrated version of the DOUBLET prototype and fully exploit its superior capabilities.
