Problems solved by technology

However, for different environments, the imaging of the target object is also different. For example, under strong light, the target object itself is very clear. After the image intensifier is used to enhance the image, it will make the obtained image whitish and reduce the clear goals

Embodiment 1

[0058] In embodiment 1, when the external environment is bright enough, strong light is radiated through the target surface, enters the night vision device, and is focused on the photocathode surface of the image intensifier under the action of the strong light objective lens. Target imaging acquires image brightness data in units of frames and compares it with the set standard brightness threshold to detect the gain coefficient, and the monitoring unit judges the control of the control part based on the detection information of the gain coefficient of the image intensifier Execution, the actuator can execute the first trigger pole opening and closing through the judgment of the monitoring unit. The response image enhances the connection between the gain module and the first trigger pole to generate a response signal; the high-voltage management unit corresponds to the set drive signal according to the generated response signal, and is used to drive the excitation of the weak t...

Embodiment 2

[0060] In embodiment 1, when the natural light in the external environment is weak, the weak natural light is radiated through the target surface, enters the night vision device, and is focused on the photocathode surface of the image intensifier under the action of the strong light objective lens. The target imaging generated by the intensifier acquires the image brightness data in units of frames and compares it with the set standard brightness threshold to form a detection of the gain coefficient, and the monitoring unit judges based on the detection information of the gain coefficient of the image intensifier The control of the control part is executed, and the actuator can execute the opening and closing of the second trigger pole through the judgment of the monitoring unit. Response image enhances the connection between the gain module and the second trigger pole to generate a response signal; the high-voltage management unit corresponds to the set drive signal according ...

Abstract

The invention provides an imaging enhancement system for a low-light night vision device, comprising: a high-voltage power supply; an image intensifier; an image intensification modulator, the image intensification modulator is configured to be electrically connected to a voltage stabilizing unit of a high-voltage module, and the The image enhancement modulator includes an image enhancement gain module; and an image enhancement gain control module, the image enhancement gain control module includes: a first trigger pole, a second trigger pole and a control section, and the present invention can obtain Detect the brightness of the target imaging to determine whether the brightness is within the set threshold. When the brightness exceeds the set threshold, the imaging output will turn white, which will affect the quality of the imaging. At this time, it is necessary to carry out weak excitation for the imaging to Reduce the imaging brightness and then output. Similarly, when the imaging brightness is poor, the drive generates strong excitation to increase the imaging brightness.

Description

technical field [0001] The invention relates to the technical field of low-light night vision devices, in particular to an imaging enhancement system for low-light night vision devices. Background technique [0002] The low-light night vision device refers to the use of natural night sky lights such as weak moonlight, starlight, atmospheric glow, and Milky Way light at night as illumination, and with the help of a light intensifier, the weak photons reflected back from the target are amplified and converted into visible images to achieve Instruments for night observation. The important part of the low-light night vision device is the light image intensifier. The low-light night vision device includes four main components: high-light objective lens, image intensifier, eyepiece, and power supply. The principle of the device is: the weak natural light radiates through the target surface, enters the night vision device, and under the action of the strong optical objective lens...
