摘要Whereas it is impossible for aerial remote sensing camera to detect and adjust the defocusing amount during photo taking, this paper presents a plan for real-time focus detection and adjustment of remote sensing camera through the combination of liquid crystal light valve and the auto-collimation in light of the linear array sweeping camera. By opening and closing the liquid crystal light valve, the plan achieves the fast switch between the imaging mode and auto-collimation focus detection mode of the camera. Based on the equipment in the lab, the author modifies the existing lens and focus detection and adjustment system and carries out a verification test. It is verified that the modified system satisfies the precision requirement of real-time focus detection and adjustment of remote sensing camera. The precision of auto-collimation focus detection stands at 0.027mm, reaching the original focus detection and adjustment system. The real-time focus detection and adjustment method can be applied to the aerial remote sensing operation of sweeping camera to solve the problem of random defocus caused by changes to the parameters in the optical system. It also applies to the focus detection and adjustment system of remote sensor camera without the scanning mirror.
