Description
Technical field：
This patent is related to a kind of infrared high spectrum imaging system, and in particular to one kind detection muzzle flash of light and Flight Projectile light
The infrared high spectrum imaging system of spectral property.
Background technology：
From the 1990s, photodetection starts to be applied to anti-sniper hand pair as a kind of important military detection means
Anti- field.Quickly grow in recent ten years, U.S. for being on the forefront at present, Israel, countries such as France and Russia develop more
The Anti-sniper detection system of kind mechanism, three classes are divided into by its working mechanism:Acoustic detection, infrared acquisition and laser acquisition.
Acoustic detection system has very big hysteresis quality on the response time, and because detection principle restricts, acoustic detection system
System can not tell the position of multiple snipers simultaneously.Laser detection system is echo to be positioned by photodetector
, when handling remote echo, the very high-resolution imaging system of inevitable requirement, this point are difficult often to accomplish, therefore,

Flashing light temperature caused by sniping gun shooting moment muzzle reaches 1000-2200K, produces the infrared letter of high radiance
Number, and the Flight Projectile gone out after thorax can also produce infrared radiation signal due to Aerodynamic Heating.Therefore, infrared anti-sniper hand detection system
System is operated by detecting the infrared radiation signal of muzzle flash of light and Flight Projectile.Probe into muzzle flash of light and flight bullet
The favorable spectral characteristics of ball select optimal detecting band and matching frame frequency in detection system.Conventional detection muzzle flash spectrum is special
The method of property is tested by single-point spectrometer, but due to the limitation of the angle of visual field, and this detection method can only small range
The spectral characteristic of muzzle flash of light is detected, can not then be detected for Flight Projectile.The radiation characteristic of Flight Projectile is mostly to pass through
Simulated experiment carries out simulation calculation, and the spectral characteristic of this kind of simulation calculation and true bullet all has certain error.
This patent can measure the spectral characteristic of muzzle flash of light and Flight Projectile simultaneously based on high light spectrum image-forming technology, compare
It is more convenient, efficient in traditional measurement method.The measuring method of this patent is applicable not only to sniping gun, applies also for all kinds of hands
Rifle, rifle and shell etc..
