Abstract

The "ColorDazl" is a device designed to be used for testing eye and sensor dazzling, at modest range, in a package that can be carried, and with a projector that could be mounted to a lethal weapon (or if desired, to another type of non-lethal device such as a "stinger"). The Tri-Laser Module (TLM) is a completely self contained subsystem of the device containing functional 3 color (RGV) laser sources. The laser beams are transmitted to the projector by an optical fiber. A 2" or larger diameter projector produces an eye-safe beam throughout its range, yet one of sufficient Irradiance or Illuminance to potentially dazzle sensors, and the unaided eye at ranges between 20' and 200' under night-time or twilight conditions. The TLM is a single pulse laser source, which can be fired every few seconds, with computer controls which keep it eye-safe at the exit aperture, and throughout the range. The output is adjustable with varying power levels and varying pulse duration of the three colors, allowing a flickering output. The system is operated from a LapTop computer which controls the total power, and pulse lengths of each individual laser, so that the total power is below 500 mW, and the energy per pulse for all 3 beams is kept below 30 mJ per pulse. This mode of operation ensures that the device is a Class 3b source as determined by ANSI Z136 classification, and is therefore free from the limitations of Class 4 which include key lock, emission delay, audible warning, etc. With simple refinements to the ColorDazl laser controller software and new projector and receiver combinations currently being considered, a higher power dazzler could be designed in the near future that will be effective and relatively safe under brighter ambient lighting and longer range conditions.
