The invention relates to an optical coupling system for glimmer detection. The optical coupling system comprises an image intensifier, a large-aperture imaging lens and a detector which are arranged sequentially along a light path, wherein the large-aperture imaging lens comprises a receiving group, an imaging group and a diaphragm; the diaphragm is connected with the receiving group and the imaging group; the receiving group comprises a front group single lens I, front group gluing I, front group gluing II and a front group single lens II which are arranged sequentially; and the imaging group comprises a rear group single lens I, rear group gluing I, rear group gluing II and a rear group single lens II which are arranged sequentially. By the optical coupling system, the technical problems of low efficiency and difficulty in quantitative analysis in the conventional relay lens coupling system are solved, and a non-contact image transmission function between the image intensifier and the imaging detector is realized.
Description
technical field [0001] The invention relates to low-light imaging detection technology, in particular to a short-distance optical coupling system for realizing non-contact image transmission between an image intensifier and an imaging detector. Background technique [0002] Low-light detection is a technology that uses image intensification devices to intensify and image faint target optical radiation signals. The key device-image intensifier (I, I.) first appeared in the United States in the 1960s. The original intention of its development was to replace the active infrared night vision system used during World War II to achieve passive detection (using the low-light characteristics of the target itself). The development of image intensification devices has experienced many technological changes, from the early generation of products (three cascades of optical fiber boards), through the second generation of products (multiple alkali cathodes) to the third generation (galli...
