一种带照明的机载弯管相机系统设计

It is necessary to obtain high-speed dynamic image at a certain position inside an aircraft cabin so that the state of the aircraft and some parameters can be measured quantitatively. Optical axes are bent to 120 degrees at mounting position. To monitor an object inside dark and weak aircraft cabin, an annular optical illumination device is designed. In order to adapt to vibration and impact on the aircraft, anti-mechanics design is adopted. Finally it is tested and verified by experiments. To match three different color high-speed or high-definition cameras and satisfy the requirement that the optical system minimal diagonal field of view should be no less than 60 degrees, it is properly designed for the optical field of view.
