Description
Technical field
The present invention relates to a kind of laser illuminator base being easy to finely tune out light optical axis, in particular, particularly relate to a kind of laser illuminator base being easy to finely tune out light optical axis being easily achieved pitching and horizontally rotating adjustment.
Background technology
Owing to there being certain interval to exist between illumination apparatus and the imaging lens of laser night-vision device, when the minimum angle of visual field and minimum light angle, two optical axis centers are independent and separate, therefore having the existence at illumination spot center and the imaging viewing field center misaligned problem of centring, this is accomplished by carrying out adjusting alignment to it.
Existing laser night vision illumination apparatus, when its minimum light angle, coordinating the minimum angle of visual field of imaging device, spot center is all the adjustment adopting and illumination apparatus or imaging device manually carrying out horizontal tilt with being directed at of imaging viewing field center at present, so that spot center is directed at imaging viewing field center. This kind of scheme, patent documentation also has example " a kind of device adjusting alignment " the Authorization Notice No. 203324584U of motorized adjustment, but program structure is complicated, is similar to small-sized The Cloud Terrace, does not have practicality.
Owing to the installation of laser night-vision device is all installation in the daytime, and laser illuminator minimum light spot cannot be observed by day with being directed at of the minimum field of view angle of imaging, also cannot energising detection after installation. And generally these night vision devices will lift or be arranged on the eminence being not easy contact, therefore after after installation, night finds misalignment, the position also again climbing frame dress is debugged, and can only be carry out night debugging just observing hot spot. Night vision device debug that to use be very big inconvenience, especially the monitoring in traffic, for instance on expressway, operation at night is unallowed, and this just requires, night vision device carries out hot spot before the mounting one by one regulate with the inspection that is directed at of visual field, in order to detect the misalignment owing to handling process causes. Although adjustment can be checked before installing, but cannot guarantee that the phenomenon not resulting in the misalignment of hot spot visual field in the process of installation exists, once installation, if hot spot is directed at visual field deviation occurs, be accomplished by daytime dismounting, evening regulate after, then wait daytime go installation. Such installation and debugging work is cumbersome and time consuming, can increase substantial amounts of cost, be unfavorable for the large scale application of equipment.
