An 90 degree airborne flex camera system

It is necessary to obtain high-speed dynamic image at a certain position outside an aircraft cabin such that we can monitor the state of the aircraft and measure some parameters quantitatively. We have to flex optical axis for 90 degree at mounting position. To solve long distance optical path conveying, improve imaging quality, and realize clear image at centre and other areas, secondary image is adopted when we design optical system. With the purpose of adapting to vibration and high-speed wind load on the aircraft, we adopt anti-mechanics and anti-wind load design. Finally, we test and verify the design by simulation and experiment.
