Abstract

The invention discloses a wavefront active compensating device of an optical system, and belongs to the technical field of aberration compensation of optical systems. The problem that a wavefront active compensating device in the prior art is complex in structure and high in cost is solved. The wavefront active compensating device of the optical system comprises a glass optical lens, an electric control system and a plurality of temperature adjusting devices, the temperature adjusting devices are fixed to the surface of the glass optical lens, and the input power of the temperature adjusting devices is controlled by the electric control system. According to the compensating device, active compensation of lens wavefront is changed by adjusting the temperature distribution of the glass optical lens, the device is simple, the caliber is not limited, and the device is suitable for the precision optical system, and is mainly used for compensating 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...
