AI Technical Summary

Technical Problem

Existing infrared binocular telescopes require users to switch between visible light and infrared images, which is complex to operate, makes it difficult to directly overlay images, affects the convenience and accuracy of observation, and the binocular design may cause visual fatigue.

Method used

Using optical waveguide technology, infrared and visible light images are transmitted to a beam combiner for superposition. The brightness of the infrared image is automatically adjusted by detecting the ambient light intensity through a light-sensing window. The display mode can be switched by a mode knob, and the focal length can be adjusted by a focus knob. It is designed as a monocular telescope to avoid visual fatigue.

Benefits of technology

It enables simultaneous observation of infrared and visible light images, improving the convenience and accuracy of observation, adapting to various lighting conditions, reducing operational complexity, and is particularly suitable for observation at night or in low light conditions, thus broadening its application scope.
