Third generation gleam image intensifier distinguishability adjusting device and method

Abstract

The invention relates to a resolution adjuster of third-generation micro image intensifier, and relative adjusting method. Wherein, said adjuster uses tubular positioning clamper and cathode clamper to fix the third-generation micro image intensifier on the working bench inside one frame; the compressor formed by compressing handle, pressure transmission rod, rigid pressure head is mounted above the axle of adjusted intensifier; the pressure sensor is between the compressor and the cathode clamper; the detectors of two size detectors are arranged on the rigid compressing head and the sealing disc of image intensifier; when adjusting the resolution, the compressor compresses the intensifier and real-time detect the position changes of rigid compressing head and sealing disc; when the difference is same as the difference between the adhere distance of intensifier and the design value, stopping compressing. The invention can reduce the cost.

Description

technical field [0001] The invention belongs to the field of low-light image intensifiers, and mainly relates to the manufacture of third-generation low-light image intensifiers, in particular to an adjustment device and an adjustment method for the resolution of the third-generation low-light image intensifiers. technical background [0002] The third-generation low-light image intensifier is the preferred core imaging device in the current low-light night vision system. The performance of this product directly determines the overall performance of the night vision system. Improving the performance index of this product through special production methods has become the focus of many researchers. Resolution is one of the important parameters of the third-generation low-light image intensifier, and the resolution of the third-generation low-light image intensifier is affected by many factors such as the microchannel plate (MCP), the front proximity distance, and the fluoresce...

Problems solved by technology

However, the main problem of this method is that it increases the processing difficulty of the cathode input window of the third-generation low-light image intensifier, and the cost is high

Looking at the above three methods of improving the resolution of the third-generation low-light image intensifier, they are all technical measures adopted before the third-generation low-light image intensifier is assembled, but for the third-generation low-light image intensifier that has been assembled How to adjust the resolution has not yet been publicly reported
