Fusion night vision device system

Abstract

The invention provides a fusion night vision device system. The system comprises a low-light objective lens group I, a low-light objective lens group II and an infrared objective lens group, wherein the right side of the low-light objective lens group I is provided with an image intensifying tube I, the right side of the image intensifying tube I is provided with a compensating mirror, the right side of the compensating mirror is provided with an eyepiece group, and the right side of the infrared objective lens group is provided with an infrared detector; the right side of the low-light objective lens group II is provided with an image intensifying tube II, the right side of the image intensifying tube II is provided with an image combining lens, an upper part of the image combining lens is provided with a compensating lens, an upper part of the compensating lens is provided with a micro display, and the right side of the image combining lens is provided with the eyepiece group; the low-light objective lens groups and the image intensifying tubes enhance a weak target illuminated by night-sky light; the infrared objective lens group and the infrared detector detect the target according to a temperature difference or a thermal radiation difference between the target and a background or between parts of the target and display the target on the micro display; and the image combining lens fuses images acquired by the infrared objective lens group and the infrared detector and amplifies the images through the eyepiece for human eyes to observe.

Description

technical field [0001] The invention relates to the technical field of optical lens manufacturing, in particular to a fusion night vision system. Background technique [0002] Low-light technology and infrared technology are the two mainstream night vision technologies at present. Low-light technology can enhance the display of targets from starlight or other weak light sources, but it is easily affected by the surrounding environment, the contrast between scenes is small, the image is flat and the level is not enough Obviously, infrared technology can detect the weak temperature difference of objects, and distinguish people, vehicles or mechanical devices from their background in imaging, but it is only sensitive to the radiation of the target scene, and is not sensitive to the brightness change of the scene. The research on the integration of these two technologies will help to learn from each other's strengths, integrate the advantages of their respective imaging technolo...
