The optical system comprises a light beam compressing and light beam reshaping unit combined by an optical fiber and a non-spherical lens assembly for correcting the non-axisymmetry of output beams; a light beam expanding unit consisting of a negative lens assembly to prevent a phenomenon of ionization and an ablation phenomenon generating dispersion dust particles caused by laser beam focusing in a transmission process; and a collimation unit consisting of a coated lens assembly for leading the laser beam to form a collimating searchlighting beam. The invention has the advantages of high searchlighting power, good beam collimation property, small volume, light weight and good practicability and is capable of observing a distant target object 2-3km far away at night.
Description
Technical field
The present invention relates to a kind of optics searchlighting device, specifically refer to a kind of infrared night vision search lighting apparatus, refer in particular to a kind of infrared night vision laser searchlighting machine.
Background technology
Realize that by means of the photoelectronic imaging device a kind of technology that night vision is observed is called night vision technology, night vision technology comprises lll night vision and two aspects of infrared night vision.The lll night vision technology claims the image intensifying technology again, is by having the night vision goggles of image intensifier tube, and the weak target of optical illumination strengthens to night, for the photoelectronic imaging technology of observing.Infrared night vision is divided into again: passive type and active.The passive infrared night vision technology is poor by means of the temperature difference or the radiation of infrared radiation light beam of self emission between background or the target object each several part, realizes the observation of target object; The active infrared night vision technology then is initiatively to shine target object by infrared radiation source, utilizes the infrared beam of target object reflection to realize the observation of target object then.The active infrared night vision technology is not subjected to the restriction of the infrared spectrum of observed object self radiation, relatively improved the signal to noise ratio (S/N ratio) that target object is caught, and can be according to the spectral characteristic of active radiation source, the more perfect image capture process system of configuration one cover is to improve the performance of total system.
The initial normal infrared light supplies such as Halogen lamp LED, Nernst glower that adopt of active infrared night vision, these light source volumes are big, power consumption big, disguise is poor, thereby poor practicability, are difficult to promote, and progressively eliminated.Occurred on the market in recent years much with the active night vision searchlighting equipment of light emitting diode (LED) as light source, broken through the shortcoming that volume is big, power consumption is big, be a progress technically, but this kind equipment is because the luminous energy of luminotron is less at present, its operating distance is less, usually have only tens meters, can not realize that the observation of long-range (2-3km) target monitors.
Summary of the invention
The present invention is directed to the observation that realizes long-range (2-3km) target object and monitor requirement, propose a kind of infrared night vision laser searchlighting machine, searchlighting power is big, can be implemented in the observation supervision of night to the remote object object of 2-3km, and volume is little, in light weight, practicality is good.
A kind of infrared night vision laser searchlighting machine of the present invention is characterized in that: as active infrared night vision search lighting apparatus light source, it is 800-980nm that described laser diode is selected operation wavelength with infra-red laser diode (LD).Output power is determined by the distance that will shine.This infrared night vision laser searchlighting machine possesses the function of the remote object object of observing 2-3km.
Described infrared night vision laser searchlighting machine, comprise that mainly one is the optical system and the LD heat conducting and heat radiating device of light source with infra-red laser diode (LD), described optical system comprises: a light beam that is combined into by optical fiber and non-spherical lens group compresses and the beam shaping unit, to proofread and correct the nonaxisymmetry of output beam; The one beam expander unit of being made up of negative lens group ionization occurs and produces the ablation phenomen of disperse grit to prevent laser beam from focusing in transmittance process; The one collimation unit of being made up of the coated lens group makes laser beam form a branch of quasi-parallel searchlighting light beam.
Because the output beam of laser diode is non-rotational symmetry type, the divergence of the light on level and the vertical both direction differs 4-6 doubly, and common optical mirror slip is the rotational symmetry type, in order to obtain collimated light beam preferably, reduce optical energy loss to greatest extent, must compress and shaping the original beam of laser diode output.
Infrared night vision laser searchlighting machine of the present invention, adopting infra-red laser diode (LD) is light source, and searchlighting power is big, and beam collimation is good, can be implemented in the observation of night to the remote object object of 2-3km, and volume is little, in light weight, practicality is good.
