A circuit structure for realizing vacuum refrigeration of an imaging terminal, which relates to the field of photoelectric imaging technology, and solves the problem that the existing vacuum equipment of the imaging terminal needs to place all the electronic systems of the imaging terminal in a closed cavity, and the vacuum cavity is huge and is not conducive to the later stage. Electronic system maintenance, testing, modification and upgrading, including focal plane components, power supply and imaging control components, and temperature control cold components; the CMOS photodetector end of the focal plane component is placed in a sealed vacuum cavity, and the focal plane component uses a flexible circuit board. The flexible circuit board is connected to the high-density inter-board connector through the airtight vacuum chamber, and the high-density inter-board connector is connected to the power supply and imaging control components; a temperature control cold assembly is installed outside the vacuum chamber; the present invention uses the flexible circuit board It passes through the airtight chamber and is connected to the back-end circuit system. There is no electronic device in the vacuum chamber to release gas, and the vacuum degree can be maintained for a long time. It is not necessary to carry a vacuum pump for repeated use. At the same time, it has the characteristics of simple structure and high reliability.
Description
Technical field [0001] The present invention relates to the field of photoelectric imaging, and more particularly to a circuit structure that is simple, efficient, reliable to realize the imaging terminal vacuum refrigeration. Background technique [0002] The imaging terminal for ground astronomical observations and weak light detection requires depth cooling to zero 20 degrees or less to reduce dark currents, and improve detection capabilities. In order to prevent water vapor in the air, it is necessary to make the imaging terminal to make the imaging terminal first. However, due to the complexity of the imaging terminal circuit system, there are many devices, the vacuum of the factory is gradually decreasing in subsequent use due to the sealing degree, the components themselves slowly release gas, and the refrigeration requirements cannot be met. [0003] At present, the universal solution of domestic and foreign manufacturers is to fit the external vacuum equipment for imagin...
