Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example figure 1 As shown, the present invention will be mainly applied in the conformal infrared concave optical system. It can be widely used in modern investigation, rescue and other fields.

[0021] Such as figure 1 As shown, a conformal infrared concave optical system containing an active optical element deformable mirror of the present invention comprises a rotationally symmetrical aspheric conformal fairing (1), a fixed lens group (2), an active optical element deformable mirror (3 ) and the detector image plane (4); in the direction of light propagation, the conformal fairing containing the rotationally symmetrical aspheric surface and the fixed lens group are perpendicular to the horizontal optical axis. The active optical element deformable mirror forms an angle of 45° with the optical axis. The detector image plane is parallel to t...

Abstract

The invention relates to a conformal concave infrared optical system with deformable mirror, which belongs to the technical field of optical instruments. The system contains a rotary and symmetrical non-spherical dome, an optical imaging system, an active optical element deforming mirror and a detector image face. The system adopts a special non-spherical dome that accords with hydrodynamic to achieve good hydrodynamic performances. Through the use of the active optical element deforming mirror, the asymmetric aberrations of the special non-spherical dome can be corrected and local concave images with high resolution can be formed on different visual fields. The system of the invention meets the performances of medium dynamics and has a simple structure; with reduced data transmission quantity of target image data, it can be widely used in the field of investigation and rescue.

Description

technical field [0001] The invention belongs to the technical field of optical instruments, and relates to an infrared small concave optical system including an active optical element deformable mirror and a conformal fairing, which is especially suitable for target detection and rescue. Background technique [0002] Infrared imaging technology plays an increasingly prominent role in modern investigation and rescue, and the system is also developing towards the trend of miniaturization and high-speed flight. The small concave optical system simulates the characteristics of small concave imaging of the human eye. By introducing active optical elements to simplify the optical system to achieve local high-resolution imaging of the details of the target, the amount of imaging data in the system is relatively small, which is convenient for transmission and makes the optical system Smaller and lighter, it is very suitable for remote control and other applications that have high re...
