Abstract

The invention discloses a long-wave infrared continuous-zooming online fast compensation installing and adjusting device and method. The compensation device comprises a reflecting infrared collimator (101), a reflector (102), a black body (103), a calibration target (104), a long-wave infrared continuous-zooming lens (105), an adjusting device (106), a detector (107), a control circuit (108) and a display (109), and the long-wave infrared continuous-zooming lens (105), the adjusting device (106) and the uncooled infrared detector (107) form a relatively independent subsystem. The device solves the problem of defocusing caused by zooming process of the infrared continuous-zooming lens, installing and adjusting efficiency of the high-accuracy continuous-zooming lens is improved, installing and adjusting cost is reduced, and damage risks of the lens caused by repeatedly disassembling and assembling in the assembly and calibration process are avoided.

Description

technical field [0001] The invention belongs to the technical field of infrared continuous zoom compensation, and in particular relates to a long-wave infrared continuous zoom online fast compensation device and method. Background technique [0002] The infrared continuous zoom lens is an optical instrument that can change the focal length at will within a certain focal length range, and can maintain high-quality, clear images and coherent movements during the entire zooming process. [0003] According to its all-weather observation characteristics, the infrared continuous zoom lens will be more and more used in military strikes, security monitoring, criminal investigation and anti-smuggling, forest fire prevention, medical diagnosis, wild animal scientific research and other fields. [0004] The current infrared continuous zoom lens usually adopts a 5-piece optical structure, including a front fixed lens, a zoom lens, a compensation lens, a rear fixed lens, and a focus lens...
