For the calibration system, a collimator is used to give white target, dim light target or IR target at infinity. Through the binocular photoelectric equipment and optical axis translation device, the two parallel lights will be incident to the area array CCD, and the target images are converted into digital image information by the CCD and frame grabber, which will be put into the computer, with which the optical axis deviation can be calculated. Then by referring to the mathematical model, the computer can give the optical axis correction program and assist in completing the parallel correction. The system is suitable for a variety of optoelectronic equipments; it can realize auto detection and display the optical axis deviation in digital form, obtaining good versatility and expansibility.
