Embodiment 1

[0041] The reflective dual-band low-light imager in this embodiment is used to detect the corona of the high-voltage equipment and determine the location where the corona is generated.

[0042] "Solar blindness" is the blind area of ​​sunlight. In the solar spectrum, ultraviolet light with a wavelength between 240 and 280nm is strongly absorbed by the ozone layer. After reaching the ground, the solar radiation intensity of this band is close to zero, so this band is called For the sun-blind ultraviolet band. Since the solar-blind ultraviolet imaging detection technology is not interfered by the background noise of the sun, even in the daytime or under indoor lighting conditions, it can still detect and image faint ultraviolet targets, and has obvious advantages in many fields of application.

Abstract

The invention discloses a reflecting-type double-band low-light imaging instrument, and the instrument comprises a reflecting-type ultraviolet band imaging system (a), a visible light band imaging system (b), and an image fusion unit (11) which enables an image obtained by the reflecting-type ultraviolet band imaging system (a) and an image obtained by the visible light band imaging system (b) to be fused in one image. The instrument can achieve the imaging of the same target at an ultraviolet band and a visible light band, has a monitoring function, is simple in structure, is reasonable in design, has no chromatic aberration, and is high in detection accuracy.

Description

technical field [0001] The invention relates to the technical field of ultraviolet low-light imaging, and in particular provides a reflective dual-band low-light imager, which is suitable for space, national defense and civilian fields. Background technique [0002] With the development of ultraviolet imaging technology, imaging detection equipment based on it is widely used in various occasions, especially for dual detection of weak radiation such as corona generated by ground-launched missiles, high-speed moving objects, and high-voltage transmission lines. Band imaging to monitor the location and radiation characteristics of low-light targets. With the deepening of ultraviolet imaging technology research, long-distance ultra-weak ultraviolet signal monitoring has increasingly become an important research direction of ultraviolet imaging technology. [0003] There are mainly two key technologies in the manufacture of ultraviolet imaging equipment: 1. Ultraviolet light fil...
