针对目前大型平行光管成像质量监测的现状,本文提出了一种对平行光管进行实时监测的新方法,验证了这种监测方法的可行性.该方法根据光管自准检测原理,采用小平面镜对光管像质进行实时监测,计算了在一个焦深范围内小平面镜转角误差大小.实验结果证明在一个焦深范围内用精度0.02"的自准直仪,可将小平面镜转角误差控制在0.2"以内,对大型平行光管起到了进行实时监测的作用.大型平行光管在空间遥感设备中运用广泛,此检测光管像质的方法在工程上将起到积极的作用.

To monitor the imaging quality of the large-scale collimator, a new method for monitoring the large-scale collimator in real time is proposed, and feasibility of the method is verified. Based on the principle of autocollimating detection, the method uses small plane mirrors to monitor the imaging quality of collimator in real time. The error of the rotating angle of small plane mirror within one focal depth is calculated, and the method demonstrates that the error of the rotating angle of small plane mirror can be controlled within the 0.2" in one focal depth by using an autocollimator whose accuracy is 0.02". It plays a role in real time monitoring to the large-scale collimator. The large-scale collimator is widely used for the space remote sensing equipment, and the method for monitoring the collimator will act an active rote in the engineering.
