Abstract

The invention discloses an optical system wavefront active compensation device, which belongs to the technical field of aberration compensation of optical systems. The problem of complex structure and high cost of the wavefront active compensation device in the prior art is solved. The optical system wavefront active compensation device of the present invention includes a glass lens, an electric control system and a plurality of temperature adjustment devices, the plurality of temperature adjustment devices are fixed on the surface of the glass lens, and the electric control system controls the input power of the plurality of temperature adjustment devices. The compensation device of the present invention changes the active compensation of the lens wavefront by adjusting the temperature distribution of the glass lens. The device is simple, has no limitation on the aperture, and is suitable for precision optical systems, mainly for supplementing the Zernike aberration of the optical system.

Description

technical field [0001] The invention relates to an optical system wavefront active compensation device, which belongs to the technical field of aberration compensation of optical systems. Background technique [0002] With the development of optical technology, the resolution of the optical system is generally improved, and the imaging quality is also continuously improved. However, due to the influence of factors such as processing errors, gravity deformation, and temperature changes, the actual integrated optical system may not meet the design requirements. This makes the wavefront compensation device of the optical system very necessary. [0003] In the prior art, optical system wavefront active compensation devices mainly include active optical compensation devices based on deformable mirrors and adaptive optical compensation devices such as liquid crystal self-adaption. However, these two devices require additional mechanical devices or optical systems. Cause device st...
