Problems solved by technology

In addition, compared with laser emitter-type night-vision devices, infrared light-emitting diode-type night-vision devices are costly and bulky, and their power consumption and size make it difficult for such night-vision devices to be miniaturized and mobile
It also cannot be used effectively in the environmental conditions of dense fog, rain, snow, smoke and dust
ZL00220524.6, etc. are night vision devices using image intensifiers, without artificial light sources, and must be used in a weak light environment, and in a near-total black environment, that is, the illuminance is lower than 2×10 -4 It cannot be observed when the black body space is in the LX environment
Environmental conditions such as dense fog, heavy rain, dense snow, dense smoke, and dense dust have adverse effects on the observation effect of such night vision devices with image intensifiers but without artificial light sources, but the observation effect is stronger than that of infrared light-emitting diode night vision devices. video device

Abstract

The active combined laser observation system includes objective combination, eye piece combination or photographic film unit or electronic imaging unit, image enhancer, imaging interface, laser and power source box. It may be used in target observation, film photography or electronic imaging in the distance of 1.5-100 Km under different lighting condition except in heavy fog, dense smoke and very dusty environment.

Description

technical field [0001] The invention relates to an active artificial light source observation system, in particular to an active laser combined observation system, which belongs to the technical fields of optical information and photoelectric imaging. Background technique [0002] The artificial light source of the night vision device described in existing ZL: 00263526.7, 96243593.7, 97240971.8 etc. is an infrared light emitting diode, and the electric-optical efficiency of this light source is low. For example, the effective irradiation distance of a 500mw infrared light-emitting diode for night vision observation is about 20m, and the effective irradiation distance of a 500mw laser transmitter for night vision observation is about 800m. The maximum effective night vision observation distance of infrared LED night vision devices is 1000m, while the maximum effective night vision observation distance of laser transmitter night vision devices is 100Km. In addition, compared ...
