Hartmann sensor zooming collimation lens matched with pupils

Abstract

The invention relates to a Hartmann sensor zooming collimation lens matched with pupils, and belongs to the field of adaptive optics, active optics and heavy caliber telescope wavefront detection. The Hartmann sensor zooming collimation lens matched with the pupils solves the technical problem that a Hartmann sensor collimation lens in the prior art cannot meet the requirement for quick and frequent switching. The Hartmann sensor zooming collimation lens matched with the pupils is composed of a zooming mirror set and a compensating mirror set. The zooming mirror set and the compensating mirror set are driven by a cam mechanism to move in the direction of an optical axis so that the focal length of the collimation lens can change continuously, and outgoing beams can be kept collimated all the time. The zooming mirror set and the compensating mirror set are respectively formed by one dual balsaming lens. The Hartmann sensor zooming collimation lens overcomes the defect that a fixed focal length of the Hartmann sensor collimation lens limits the uniqueness of sensor capability; an optical system which is simple and easy to adjust and corresponding mechanisms are used so that the focal length of the collimation lens can be switched to be adapted to wavefront detection on different conditions with different performance requirements.

Description

technical field [0001] The invention belongs to the fields of adaptive optics, active optics and large-aperture telescope wavefront detection, and in particular relates to a Hartmann sensor zoom collimator lens satisfying pupil matching. Background technique [0002] The Hartmann wavefront sensor is an optical measurement device that obtains phase information of the wavefront by measuring the slope of the wavefront. Due to its good environmental adaptability, real-time measurement, and the ability to directly use target light sources such as starlight for measurement, it is widely used in active optics. , adaptive optics, and large-aperture telescope detection have important applications. As part of the Hartmann wavefront detection relay optical system, the functions of the collimating lens include: (1) collimating the beam; (2) making the measured beam aperture meet the sensor’s spatial sampling frequency requirements; (3) realizing the Pupil matching, which images the pup...
