Summary of the invention
Manually carry out the limited deficiency of Nonuniformity Correction service condition in order to overcome infrared camera; The invention provides a kind of electric operator; It is a kind of infrared camera Nonuniformity Correction device; In the infrared camera start-up course, automatically reference blackbody is cut from light path/cut out, and then accomplished the Nonuniformity Correction processing of camera.It is that mechanism provides straight line power that the present invention adopts the circular pipe type electromagnet, drives shadow shield indirectly through crank mechanism and realizes blocking with open of light path.
The technical scheme that technical solution problem of the present invention is adopted is following:
A kind of infrared camera Nonuniformity Correction device comprises pedestal, circular pipe type electromagnet, crank mechanism, pin, closure state stop screw, gag lever post, duty stop screw and shadow shield; Said crank mechanism comprises crank, cam and bent axle, and the bent axle hinge joins on pedestal, can in pedestal, freely turn round; Crank and cam connect firmly on bent axle, and the axis of symmetry nn of the axis of symmetry mm of crank and cam becomes 60 ° of angles; The circular pipe type electromagnet is hinged through pin and crank, and cam drives through crank and bent axle and carries out the reciprocating rotating motion; Gag lever post connects firmly on pedestal, with the rotating range of restriction cam; Shadow shield connects firmly on cam, can be with the cam reciprocating rotating; The closure state stop screw connects firmly on cam through screw thread, and when shadow shield is in closure state, contacts with gag lever post; The duty stop screw connects firmly on cam through screw thread, and when shadow shield is in running order, contacts with gag lever post.
The invention has the beneficial effects as follows: adopting the circular pipe type electromagnet is that device provides straight line power, drives shadow shield indirectly through the crank mechanism that is made up of crank, bent axle and cam and realizes blocking with open light path; Simple in structure, reliable and practical, than the outstanding advantage of circumference formula and orthoscopic switching device shifter be: spatial volume is little, is more suitable for the serious limited use occasion in space.
