Technical field
The present invention relates to a kind of device of surveying light laser long-distance plane intensity, can obtain the face intensity data of intense laser beam after remote propagation in atmosphere, belong to laser technology field.
Background technology
In fields such as laser ranging, communication and laser weapons, laser beam is all propagated at the outside atmosphere middle and long distance, and the face intensity of propagating terminal light beam is an important parameter of laser, and how testing this parameter becomes this field technical issues that need to address.Application number is that an one Chinese patent application of 02114632.2 discloses the scheme of a key name for " online superlaser energy and light power density space-time distribution measuring system "; This system can on-line measurement go out the superlaser optical power density in time with the spatial variations result, also can obtain total energy value through calculating.This system is particularly suitable for that facula area is big, fluorescent lifetime is short, output energy and the high continuous wave high-energy laser of fluoridizing infrared bands such as deuterium, oxygen iodine of power density, also can be used for carbon dioxide, the higher continuous wave laser of YAG constant power density.Yet measured data are all accurate inadequately, and can only measure indoor, and test result lacks practical significance.
Summary of the invention
Its purpose of the present invention is, realize the high precision measurement through the surface density of light laser after the remote propagation in atmosphere, and test can be carried out in the open air, and for this reason, we have invented a kind of device of surveying light laser long-distance plane intensity.
The device of the present invention's detection light laser long-distance plane intensity is characterized in that; Some energy probes in the energy detection system are evenly distributed on the diffuse reflection target plate, are the radio communication relation between data transmitter in the energy detection system and data and the picture receiver; Imaging system is positioned at diffuse reflection target plate the place ahead at a distance; CCD camera in the imaging system is concentrated one's gaze on the diffuse reflection target plate; Be the wire communication relation between image transmitter in the imaging system and data and the picture receiver, be the radio communication relation between synchronous signal receiver in the imaging system and the isochronous controller; Data and picture receiver, isochronous controller all with the computing machine wired connection.
Its technique effect of device of the present invention's detection light laser long-distance plane intensity is; The work of computer control isochronous controller; Isochronous controller is sent synchronizing signal to trying laser instrument and imaging system simultaneously with wireless mode; So passed through atmosphere irradiation diffuse reflection target plate by the long distance of examination laser instrument emission light laser, imaging system is taken the light laser light spot image on the diffuse reflection target plate synchronously, and is sent to data and picture receiver.Some energy probe detections in the energy detection system arrive several relevant with laser intensity energy values of light laser hot spot everywhere, and are sent to data and picture receiver.Data and picture receiver are transferred to computing machine with picture signal that receives and energy value.The computing machine one side as gradation data, obtains laser intensity by energy value with picture signal on the other hand.Because these energy values are from light laser hot spot diverse location, the light laser hot spot is different in these images of positions gray scales, can access the corresponding laser intensity of the different gray scales of light laser light spot image thus.Computing machine obtains the corresponding laser intensity of light laser light spot image everywhere according to this relation, thereby also just obtains the face intensity of light laser.Because many ingredients are with wireless mode work in the present invention's the device; Make the present invention's device can be fit to open-air long distance and complex-terrain detection; For example; Distance by examination laser instrument and diffuse reflection target plate can reach more than 1000 meters, and the distance of imaging system and diffuse reflection target plate can reach 200 meters.In addition, the detection accuracy of the present invention's device depends on the detection accuracy of energy probe and the resolution of CCD camera, and is enough to guarantee required precision and resolution about the prior art of this respect, and therefore, the measuring accuracy of the present invention's device is very high.
