Abstract

The invention relates to a medium-wave infrared continuous zooming camera shot and a control method thereof. The mechanical structure of the camera shot comprises a zooming assembly, a focusing assembly and a detector assembly which are installed on and connected to a connecting bottom plate sequentially from left to right. The zooming assembly comprises a front fixed lens A, a variable-magnification lens B, a compensation lens C, a rear fixed lens D, and a zooming mechanism. The focusing assembly comprises a secondary imaging lens group E and a focusing mechanism. The detector assembly comprises a baffle switching mechanism, a detector and a detector frame. In the optical system of the lens, the front fixed lens A, the variable-magnification lens B, the compensation lens C, the rear fixed lens D and the secondary imaging lens group E are arranged sequentially from left to right along the incident direction. The invention provides a medium-wave infrared continuous zooming camera shot which has the advantages of high imaging quality, high spatial resolution, small size, light weight, and vibration and impact resistance.

Description

technical field [0001] The invention relates to a mid-wave infrared continuous zoom lens for live recording and tracking and a control method thereof, belonging to the lens field. Background technique [0002] The infrared optical system can detect, locate and track the infrared radiation of the target object, and convert the infrared radiation distribution image of the target object into a visible light video image through photoelectric conversion, signal processing, image processing and other means. The bands covered by commonly used infrared lenses are medium wave 3-5μm and long wave 8-12μm. In the infrared band, there are few materials to choose from. The commonly used materials for medium wave 3~5μm include silicon, germanium, zinc selenide, zinc sulfide and chalcogenide glass, etc.; the commonly used materials for long wave 8-12μm include germanium, zinc selenide, zinc sulfide and sulfur Department of glass etc. [0003] Generally, the infrared zoom imaging optical s...
