Abstract

The invention relates to a large visual scanning infrared optical system containing an aspherical fairing, belonging to the technical field of optical instruments. The system comprises a rotary symmetrical aspherical fairing, an achromatic rotary Risley prism pair, an optical imaging system and a detector image surface. The special aspherical fairing according with hydrokinetics is applied to the system and has favorable hydrodynamic performance; the detected target is subjected to dynamic scanning and imaging by using an optical wedge; an imaging optical system in a subsequent light path is fixed; and a low-temperature coil and electronic equipment do not pass through a rotating mechanical device. The large visual scanning infrared optical system meets the characteristics of medium dynamics, has the advantages of favorable quality of system imaging, light weight, shortness in length and simple structure, can reach a scanning visual field with more than 60 degrees and can be widely applied to the fields of investigation, rescue and the like.

Description

technical field [0001] The invention belongs to the technical field of optical instruments, and relates to a large-field-of-view scanning infrared optical system including an aspheric dome, which is especially suitable for large-scanning field-of-view infrared focal plane imaging. Background technique [0002] Infrared imaging technology plays an increasingly prominent role in modern investigation and rescue. As an imaging component, the optical fairing of the thruster seeker needs to meet the requirements of low hydrodynamic resistance while meeting the image quality requirements of the optical detection system. The outer surface of the rotationally symmetrical aspheric optical dome has a sharper arched shape, which can better meet the requirements of the dynamic performance of the medium. However, when the optical system behind the fairing performs tracking and scanning imaging on a certain range of field of view, since the surface of the fairing participating in the imag...
