Micro target detecting system with long-focus large field no-movable part

Abstract

The invention is a tiny object detecting system with long focus distance and large view field, which belongs to target detecting technology field. In order to research the tiny target detecting system without moving part and with large view angle and long focus distance, in order to discover, incriminate and trace the space target, the invention discloses a tiny target detecting system, which includes long focus distance optical tracing imaging system and wide view angle searching system, the long distance optical tracing system includes the first reflector, the second reflector and the first light sensitive device; the two systems are connected coaxially, thus the wide view angle lens, the second light sensitive device, the second reflector, the first reflector and the first light sensitive device are on the same axis. The invention has no moving parts, thus the reliability of the whole system can be upgraded.

Description

technical field [0001] The invention relates to a target detection system and belongs to the technical field of target detection. Background technique [0002] A camera with a long focal length or a telephoto system is suitable for shooting long-distance objects, but has a small field of view; a wide-angle camera has a short focal length and a large field of view, and is suitable for shooting close-up and large-scale objects. To observe long-distance and large-scale scenes requires a long focal length and a large field of view, which cannot be met by a single camera with a long focal length or a telephoto system or a camera with a wide viewing angle. Contents of the invention [0003] The purpose of the present invention is to develop a micro-target detection system with long-focus optical tracking imaging and wide-angle search capabilities without moving parts, so as to discover, identify and track space targets. [0004] The technical solution of the present invention i...

Problems solved by technology

[0002] A camera with a long focal length or a telephoto system is suitable for shooting distant scenes, but the field of view is small; a camera with a wide field of view has a short focal length and a large field of view, and is suitable for shooting close-up and wide-ranging scenes

To observe long-distance and large-scale scenes, a long focal length and a large field of view are required, and a single long-focus camera, telephoto system, or wide-angle camera cannot meet the requirements
