Description

A kind of infrared eye is proofreaied and correct and the test all-purpose frock

Technical field

The utility model belongs to a kind of infrared eye to be proofreaied and correct and the test all-purpose frock, is specifically related to a kind of supporting mechanism when infrared eye is proofreaied and correct and tested.

Background technology

Infrared imagery technique is that a kind of difference of utilizing the radiation of scenery self each several part obtains can be for the technology of visual image (or sequence video signal).Infrared thermal imaging instrument and system have the ability through smog, dirt, mist, snow and identification camouflage, are not subjected to high light on the battlefield, dazzle interference and blinding can carry out remote, round-the-clock observation.

Infrared image even clear most important to target observation, identification and identification.Infrared eye is the core component of infrared imaging system.Yet, stare the focal plane infrared eye in process of production for present, because the restriction of material and technology, can there be some defectives in its focal plane, causes the unevenness of detection, in use must carry out nonuniformity correction.Nonuniformity correction adopts the two-point calibration method, and this calibrating method need receive the emittance of black matrix when high low temperature and resolve correction parameter.The key of calibration effect quality is that detector respectively responds pixel and whether can receive identical emittance, promptly requiring in detector field of view to receive black matrix, to send emittance be uniform, under the situation that guarantees the material emissivity of black matrix unanimity own, relative position relation for detector and blackbody radiation face is most important, if receive other emittance except that black matrix in the detector field of view, will certainly cause the uneven result of received energy, the effect correction effect.In guaranteeing all even actual use of blackbody radiation flooring, the requirement of heating and cooling time is seen, the blackbody radiation face that requires native system to use is less, and the visual field of detector is bigger, so should detector be pressed close to the blackbody radiation face as far as possible, but detector is infinitely near radiating surface, will certainly cause the broken possibility of contact to window, cause the permanent damages of detector, on the nargin basis of area, detector field of view and the assurance detector window safety of accurate Calculation blackbody radiation face, detector and blackbody radiation face all need accurately control at the relative position of several directions.If can design and produce a kind of special-purpose frock of proofreading and correct, the position of detector and blackbody radiation face is accurately located, will improve accuracy and correction efficient that the detector black matrix is proofreaied and correct greatly.

The utility model content

The purpose of this utility model provides a kind of infrared eye that can improve greatly and proofreaies and correct the tool structure of surveying accuracy and proofreading and correct efficient.

The utility model integral body is that a kind of infrared eye is proofreaied and correct and the test all-purpose frock, wherein, integral body is rectangular structure, two relative minimum lateral places empty, end face center processing stopper slot, be used to place detector, process outstanding stopper on the side of frock next-door neighbour black matrix face.

Aforesaid a kind of infrared eye is proofreaied and correct and the test all-purpose frock, wherein, stopper slot guarantees that the detector axis can be positioned at the center of proofreading and correct pedestal on surface level, and detector is vertical with black matrix, stopper is used for fixing the upright position of pedestal and black matrix face, and lateral surface that frock and black matrix are adjacent and black matrix framework outer boundary are fitted, and stopper cooperates with black matrix framework inside edge, black body locus is fixed, thereby make the window of detector just in time be positioned at the central point of black matrix face; The sideline of stopper slot guarantees that detector is apart from the distance of window apart from black matrix face 15mm.

Aforesaid a kind of infrared eye is proofreaied and correct and the test all-purpose frock, and wherein, described stopper slot is a rectangle, and described stopper is a rectangle, and described infrared eye is proofreaied and correct and test all-purpose frock making material selection aluminum component.

The utility model has the advantages that: proofread and correct the accurate location that pedestal has been realized detector and extend blackbody position by using, improved the accuracy that detector is proofreaied and correct; Reduced owing to put cause correction data is influenced not in place, avoided simultaneously because the risk that detector window and blackbody radiation face too closely cause window to damage; Next has reduced the setup time before the test, as long as detector put into the base-plates surface stopper slot just can be tested, need not to adjust the position, has improved correction efficient greatly, has used the aluminum component material, and is light, be easy to process.
