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.

Camera design in ultra-low temperature vessel

According to special application, surveillance camera working in the ultra-low temperature and high pressure vessel is designed. By request of optics and electronics system on temperature, research focus on the design from selection of the structure material, thermal insulation, the adaptability of optical system in the ultra-low temperature and high pressure environment. Finally, It is confirmed that opto-Mechanical structure with double layers thermal insulation of PIPA and ITO optical window have benefit on thermal insulation for the camera working in this ultra-low temperature(-196°C) and high pressure(0.5MPa) environment. All the opto-Mechanical material which may be contact with ultra-low high pressure liquid can also be consistent with liquid.
