System and method for reducing inner surface roughness of microchannel plate channel

Abstract

The invention provides a system and method for reducing inner surface roughness of a microchannel plate channel. The system comprises a femtosecond laser, a modulation optical component, a microchannel plate fixing frame, an attitude adjustment assembly, a first motor; the femtosecond laser is used for generating and outputting pulse optical signals; the modulation optical component is arranged on the light emitting side of the femtosecond laser and is used for converting a pulse optical signal generated by the femtosecond laser into a parallel pulse light beam; the microchannel plate fixingframe arranged to fix a microchannel plate to be processed, the microchannel plate is an optical element with a microporous structure, and each microporous structure forms a channel; the attitude adjustment assembly fixed to the microchannel plate fixing frame; the first motor is connected to the posture adjusting mechanism through the driving mechanism and transmits the rotating torque to the posture adjusting mechanism, so that the posture adjusting mechanism drives the posture adjustment of the microchannel plate fixing frame, thus adjusting the angle and position of the parallel pulse beamentering the microchannel plate channel for purging. Through the uniform laser pulse purging, the inner surface roughness and dark current density of the microchannel plate can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of micro-channel plates, in particular to a system and method for reducing the roughness of the channel inner surface of a micro-channel plate. Background technique [0002] As a low-light night vision technology that develops human vision, it plays a huge role in military applications such as night observation, aiming, driving, and navigation. Night vision technology is a technology that uses the method of expanding the observer's vision to realize nighttime covert observation under the condition of low illumination at night. Based on the principle of optoelectronic imaging or conversion, various low-light night vision devices are manufactured by using key or core components such as low-light image intensifiers, which overcome the limitations of the human eye under low illumination and limited spectral response, and open up the human eye. Vision function, to achieve the purpose of observing distant targets...

Problems solved by technology

[0004] In the prior art, the channel of the micro-channel plate is formed after the core material is corroded, and the roughness of the inner surface of the channel of the micro-channel plate is determined when the channel is formed. Once the etching process is completed, the next process is processed. The roughness of the inner surface of the microchannel plate is difficult to be changed
