Double spectrum image detector

Abstract

The double spectrum image detecting instrument includes ultraviolet imaging system, background imaging system, signal acquisition device and signal processing unit. The ultraviolet imaging system includes imaging objective, two-color spectroscope, ultraviolet image enhancer, coupling lens and video camera. The background imaging system include the imaging objective, the two-color spectroscope, reflector, one other coupling lens and one other video camera. The light beam from the imaging objective is divided in the spectroscope into one ultraviolet beam and one background beam; the ultraviolet beam is imaged on the input plane of the enhancer and the spectral converted and brightness enhanced image is imaged in the first video camera; the background light beam is reflected, coupled and imaged in the second video camera; and two path of images are further processed, superposed and restored.

Description

1. Technical field: [0001] The invention is an ultraviolet dual-spectrum image detector, which belongs to the innovative technology of the image detector. 2. Background technology: [0002] At present, the discharge detection and fire alarm monitoring of power transmission and transformation systems mainly use infrared detection systems, which have the disadvantages of weak anti-interference ability, high rate of false detection and false alarm, and can not work in the environment of strong light, so it is difficult to determine the discharge and fire. The position of the fire alarm; and the time response frequency is low, the structure is complex, and the cost is high. For this reason, in recent years, ultraviolet alarms have been gradually adopted in the discharge detection and fire monitoring of power transmission and transformation systems, but because they have no imaging function and background image signals, it is impossible to realize the positioning and discriminati...

Problems solved by technology

[0002] At present, the discharge detection and fire alarm monitoring of power transmission and transformation systems mainly use infrared detection systems, which have the disadvantages of weak anti-interference ability, high rate of false detection and false alarm, and can not work in the environment of strong light, so it is difficult to determine the discharge and fire. The location of the fire alarm; and the time response frequency is low, the structure is complex, and the cost is high

For this reason, in recent years, ultraviolet alarms have been gradually adopted in the discharge detection and fire monitoring of power transmission and transformation systems, but because they have no imaging function and background image signals, it is impossible to realize the positioning and discrimination of the fault degree, and its structure is complex and bulky. , cumbersome to operate and inconvenient to carry
