Description
Technical field
The present invention relates to a kind of active artificial light source recording geometry, particularly a kind of active laser combination observation system belongs to optical information, photoelectronic imaging technical field.
Background technology
Existing ZL:00263526.7, the artificial light source of the night-vision devices of elaborations such as 96243593.7,97240971.8 is an infrarede emitting diode, the electricity-optical efficiency of this light source is low.Effective irradiation distance when being used for night vision observation as: the infrarede emitting diode of 500mw is about 20m, and the effective irradiation distance of the generating laser of 500mw when being used for night vision observation is about 800m.The maximum effectively night vision observed range of infrarede emitting diode class night-vision devices is 1000m, and the maximum effectively night vision observed range of generating laser class night-vision devices is 100Km.In addition, compare with generating laser class night-vision devices, infrarede emitting diode class night-vision devices cost height, volume are big, and its power consumption and volume make these type of night-vision devices be difficult to miniaturization and move and use.Also can not descend effectively to use in the environmental baseline of the dense snow of the dense rain of thick fog, the dense dirt of dense smoke.ZL00220524.6 etc. are to use the night-vision devices of image intensifier, do not have artificial light source, must use having under the faint light environment, and near under the total darkness environment, be that illuminance is being lower than 2 * 10
-4Can't observe during black matrix space under the LX environment.Environmental baselines such as thick fog, dense rain, dense snow, dense smoke, dense dirt this type of is had image intensifier but do not have artificial light source the observation effect of night-vision devices adverse effect is arranged, but observation effect is better than infrarede emitting diode class night-vision devices.Duty and the observation effect of the present invention when closing generating laser is equal to this type of and image intensifier arranged but the night-vision devices that do not have artificial light source.
Summary of the invention:
The object of the invention provides a kind of observed range scope between 1.5 meters～100 kilometers, visibility good except that thick fog, dense rain, dense snow, dense smoke, dense dirt, and be illuminance 2 * 10 to faint light night is arranged until total darkness environment daytime
-11Under the black matrix space environment of LX, can carry out direct visual observation, film is taken pictures or electronics is shot with video-corder combination observation system---active laser combination observation system.
Technical scheme of the present invention is as follows.
Major technique design of the present invention: image intensifier is more than the photon of input at the light photon of the corresponding point output of image, makes the brightness of image gain, unsharp image is promoted be distinct image; But when the photon numbers of input is lower than effective working limit of image intensifier, i.e. the low complete black (illuminance 2 * 10 that for example levels off to is crossed in the brightness of observed object
-4LX～2 * 10
-11LX) under the space environment, image intensifier promptly can not effectively be worked.And the monochromaticity of generating laser emission laser is good, the choosing wavelength wide ranges, employed wavelength coverage is narrow, brightness is high, the coherence is good, good directionality, can laser beam be focused on or disperse by optical instrument; Have electricity-optical efficiency height, high-power characteristic, system can use portable power supplies to carry out mobile observation, can enlarge observation scope and observed range; Observed range of the present invention is contained 1.5 meters～100 kilometers far and near scope, be can daytime of the visibility good except that thick fog, dense rain, dense snow, dense smoke, dense dirt to there being faint light to descend until the black matrix space environment night, carry out direct visual observation, film is taken pictures or electronics is shot with video-corder combination observation system; This combination observation system has formed the system of optical observation, luminance gain, picture signal conversion, transmission and the storage of a telotism; Therefore be choose reasonable under the current techniques condition with generating laser as the active artificial light source of image intensifier.
The present invention also can be used as other correlative equipment supporting observation, take pictures, shoot with video-corder parts or supporting aiming elements.The present invention and gps system are integrated and are used, and can be used for determining that the orientation of target being observed is in particular for determining the orientation of target being observed at night.
The generating laser emitted laser wavelength of all size of this combination observation system is between 808nm～0.01mm, and determining of its concrete numerical value should be in selected concrete image intensifier be accepted limit range that wavelength allows; Can be according to the penetrability of mist, rain, snow, cigarette, dirt or the disguise of observation side are required to select needed different laser chromatography.The generating laser emitted power scope of this combination observation system all size is between 2mw～10w, and its concrete numerical value is selected, determined according to the needs of different observed ranges and scope; The generating laser emitted laser angle of divergence of this combination observation system all size is 0.2msr (milli sterad)～5msr, can reach the laser beam divergence of certain 1 scope between 0.2msr～110sr (sterad) behind the optical coupler of additional different size.Use needs night according to system, can penetrate divergencing laser also can focus on particular range or target, divergencing laser helps enlarging the observation area, and the laser that focuses on or approach to focus on helps improving the laser radiation brightness of spot area object being observed, thereby improves the observation sharpness.
