Camera Design in Ultra-low Temperature Vessel

摘要

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.
