A miniaturized high-gain low-light night vision imaging device

Abstract

The invention discloses a miniaturized high-gain low-illuminance night vision imaging device, which is mainly used for military helmet night vision devices and similar night vision products used in related industries. Its main technical scheme: the input end of the tube shell is sealed and welded with the input window, and the end of the tube shell is sealed and welded with the output end of the CMOS image sensor; the photocathode is plated in the effective area of ​​the inner surface of the input window; the microchannel plate is installed on the second side of the tube shell. Between the metal ring and the third metal ring; the CMOS image sensor is welded to the ceramic substrate, and the output end of the CMOS image sensor is connected to the readout circuit board. The invention proves through the trial that the phenomenon of low gain of the original device is fundamentally overcome, the gain of the device can be effectively improved, the miniaturization is realized, and the requirement of single-person night vision products such as military helmet night vision devices is met.

Description

technical field [0001] The invention relates to a photoelectric imaging device, in particular to a low-illuminance night vision imaging device for miniaturized high-gain electron bombardment CMOS image sensors, mainly used for military helmet night vision devices and similar night vision products used in related industries. Background technique [0002] With the development of CMOS image sensor technology, electron bombardment CMOS image sensor (hereinafter referred to as electron bombardment CMOS low-light night vision imaging device) as a new type of low-light imaging device has played an important role in safety supervision, medicine, scientific research and other fields. application. In the military night vision equipment represented by helmet night vision products, in order to meet the needs of individual soldiers for night combat, marching and observation, it is necessary to have better imaging performance under low illumination conditions, and to be small in size, lig...

AI Technical Summary

Problems solved by technology

However, the gain is only about 200 times. Due to the use of multiple electrodes and magnetic field generators, the volume and weight are large, and it is difficult to miniaturize the whole machine. Therefore, it is not suitable for military helmet night vision systems and can only be used for Detection of general weak light signals
