The Application of Tenuity Laser Radiation Detecting Technology in the Laser Warning Devices

According to the countermined objects and the characteristics of the laser warning devices. The main restriction factors of the tenuity laser detecting technology were analyzed. These factors included the contradictions of laser receiving technology at large field of view with narrow band spectral filtrating technology and aperture diameter with the field of view of the optical system adopted, the restriction of the low repeating rate of laser signal and the narrow pulse width of laser signal. In allusion to the different sensitivity requirements of different systems of laser warning devices, the tenuity laser radiation detecting technology adopted in the direct irradiation intercepting system and irradiation scattered intercepting system of laser warning devices were summarized. These are low noise detectors, low noise electro-optical contact electro-circuits and amplifier circuits, the optical system with large field of view and relative large aperture diameter, the spectral filtrating technology with large field of view. The applications of these technologies meet the sensitivity requirements of the laser warning devices.
