adjustable single-state reflectometer system

The other is the scanning system, the use of diode-pumped solid-state lasers, 32 yuan avalanche photodiode, fiber optic relay system and binary optical scanners allegedly two programs can meet the requirements. U.S. Air Force Wright Laboratory and the University of Dayton Research multispectral laser radar in which the laser output of laser radar using continuous at 1.35 ~ 5μm tunable optical parametric oscillator, pulse energy 3.3mJ, pulse width 3ns. with adjustable single-state reflectometer system, measuring the bidirectional reflectance distribution function of the target which can be laser radar clutter and the target in a hidden part of the case under the ground target imaging and identification. The RF  laser pointer  is advanced in design. The photoelectric technology of  laser pointer  is very advanced. Many countries in the development of helicopter obstacle avoidance using laser radar. U.S. Ross Dunlop ? Grumman and the Army Communications-Electronics Command Night Vision and Electronic Sensors Directorate jointly developed low altitude helicopter flight with an obstacle avoidance system. The system uses a semiconductor laser transmitter and rotating holographic scanner to detect a wide range of helicopters, the former can be barriers to information displayed in the HUD or helmet-mounted display. The laser radar system has been carried out in two helicopter pilot. In the U.S. Army Night Vision and Electronic Sensors Division under the guidance of the Army helicopter obstacle avoidance system as part of the plan, Fibertek company developed a helicopter laser radar system to detect telephone lines, power lines and the like obstacles. The laser radar sensor pod and electronic devices by the composition, the use of diode-pumped 1.54 (m solid-state lasers. Pod installed laser transmitters, receivers, scanners, and support systems. The photoelectric technology of  laser pointer  will be enhanced further.
Electronic devices from the computer, data and video recorders, time electronic systems, power conditioners, refrigeration systems, and control panel components. The laser radar system installed in the UH-1H helicopter. Germany's Daimler - Benz Aerospace in accordance with the Federal Office of Defense Technology and Procurement contract, developed Hellas obstacle detection laser radar. The laser radar is 1.54 (m imaging laser radar field of view for the 32o (32o, can detect the distance of 300 ~ 500m, more than 1cm in diameter wire and other obstacles (depending on the angle and visibility).
