Description
Technical field
The present invention relates to the optical instrument checkout equipment, particularly a kind of equipment that the plain shaft parallelism of photoelectric monitoring equipment with a plurality of optical systems is detected.
Background technology
Be furnished with simultaneously in the present large photoelectric monitoring equipment that visible light, medium wave are infrared, a plurality of optical systems such as LONG WAVE INFRARED and laser ranging, purpose is to make photoelectric measurement equipment possess multispectral section detectivity, has more strong functions.In order to finish detection and the measuring task to target, The key factor is to make all kinds of imaging optical systems parallel with the optical axis strictness of laser distance measuring system, keeps identical sensing, with the consistance and the accuracy of each system's measurements of guaranteeing the photoelectric tracking measuring equipment.Need to seek a kind of detection method for this reason, can check the collimation between all kinds of system optical axis, for the check adjustment of large photoelectric monitoring system provides foundation.The disclosed a kind of device that adopts thermal target technology that three-axle parallel of large photoelectric monitoring equipment is detected of the applicant's patented claim formerly (application number 200610016518.X), owing to adopt hot target to carry out thermal cross over, the collimation that therefore can only realize laser system and infrared system detects, can't realize the detection of laser and visible system, and reading of parallel misalignment places one's entire reliance upon by check system.
Summary of the invention
The objective of the invention is to propose the device of a kind of detection laser and visible light systematic optical axis collimation, detect to realize the laser system and the collimation of visible systematic optical axis.
The device of detection laser of the present invention and visible light systematic optical axis collimation, by the reflective parallel light tube that is arranged on the base slide unit, light source and computing machine are formed, described reflective parallel light tube constitutes in the following manner: can simultaneously correspondingly contain the laser of tested instrument and the light pipe receiving port end of visible light systematic optical axis is disposed with light damping plate downwards from bore, hyperbolic mirror, parabolic lens with center pit, half-reflecting half mirror with light pipe optical axis angle at 45, on the focal plane of the collimated light path that parabolic lens and hyperbolic mirror are formed, a CCD device is set, its target surface is centered close on the light pipe optical axis, is being provided with crosshair differentiation plate by the formed conjugate focal planes of half-reflecting half mirror place; Outside light pipe, described light source is set corresponding to crosshair differentiation plate place; The output end of image of CCD device is connected with described collecting image of computer card.
Pick-up unit of the present invention provides effective technical means for realizing to the laser and the detection of visible system plain shaft parallelism of photoelectric monitoring equipment; And the parallel misalignment of laser and visible system is handled the back automatically by computing machine and is shown, does not need to rely on tested equipment and carries out interpretation.
Description of drawings
Fig. 1 is the light path principle synoptic diagram of pick-up unit of the present invention.
Embodiment
Below the embodiment that provides with regard to accompanying drawing structure of the present invention is described in further detail.
With reference to Fig. 1, the device of a kind of detection laser and visible light systematic optical axis collimation, by the reflective parallel light tube that is arranged on the base slide unit, light source and computing machine are formed, described reflective parallel light tube constitutes in the following manner: can simultaneously correspondingly contain the laser of tested instrument and the light pipe receiving port end of visible light systematic optical axis is disposed with light damping plate 1 downwards from bore, hyperbolic mirror 2, parabolic lens 3 with center pit, half-reflecting half mirror 4 with light pipe optical axis angle at 45, on the focal plane of the collimated light path that parabolic lens 3 and hyperbolic mirror 2 are formed, a CCD device 5 is set, its target surface is centered close on the light pipe optical axis, is being provided with crosshair differentiation plate 6 by half-reflecting half mirror 4 formed conjugate focal planes places; Outside light pipe, described light source 7 is set corresponding to crosshair differentiation plate 6 places; The output end of image of CCD device is connected with described collecting image of computer card.
The principle of work of this pick-up unit is:
Before the collimated light path system that forms by parabolic lens and hyperbolic mirror, place light damping plate, on the focal plane of collimated light path, place the CCD receiver, place a half-reflecting half mirror before the CCD receiver, through the half-reflection and half-transmission mirror reflection, form a focal plane with CCD receiver position conjugate, crosshair differentiation plate is set, this crosshair differentiation plate of light illumination at this focal plane place.Adjust crosshair differentiation plate and CCD receiver, crosshair differentiation plate center and CCD target surface center all are positioned on the optical axis of collimated light path system.
Detection is during by the test examination instrument plain shaft parallelism, at first open lighting source of the present invention, illumination crosshair differentiation plate, adjustment is pointed to by the test examination instrument optical axis, make crosshair differentiation plate be imaged on the center, visual field of visible light optical system, close lighting source, open by test examination instrument Laser emission switch, the laser beam that is sent by the generating laser of test examination instrument enters the collimated light path system that is made up of parabolic lens and hyperbolic mirror after light damping plate carries out energy attenuation, converge on the CCD target surface, CCD outputs to the computer acquisition card after collecting image, after the capture card conversion, form the digitized image of hot spot, this image is again through the past background, after processing such as noise, draw the center of gravity of its hot spot by the light intensity weighting algorithm, finally obtain the collimation error of laser system optical axis and visible light system optical axis by the deviation distance at this centre of gravity place and CCD target surface center.
