Full light path aberration correction system and full light path aberration correction method based on double Hartmann sensors

Abstract

Provided are a full light path aberration correction system and a full light path aberration correction method based on double Hartmann sensors. The correction system comprises an efficient laser, a wavefront corrector, a spectroscope, a optical quality evaluation system, an inner light path Hartmann sensor, a first Hartmann sensor, a second Hartmann sensor, a data combining assembly and a high voltage amplifier. The correction method based on the correction system uses two Hartmann sensors to simultaneously measure reflection and transmission aberration of the spectroscope and uses a data combining method not relying on response arrays to transmit aberration of the spectroscope to the inner light path Hartmann sensor to control the wavefront corrector to correct the full light path aberration. The full light path aberration correction system and the full light path aberration correction method based on double Hartmann sensors has the advantages of being simple in principle, convenient to achieve, capable of resolving the problem of limit of component structure process in the prior art, capable of improving data combing rate between multiple sensors and capable of effectively promoting outlet light beam quality of the efficient laser system.

Description

technical field [0001] The invention mainly relates to the field of an all-optical-path aberration correction system and data fusion, in particular to an all-optical-path aberration correction system and a correction method based on double Hartmann sensors. Background technique [0002] In a high-energy laser system, the spectroscope is an important optical device used to connect the strong light path and the weak light measurement system. The system senses the wavefront aberration of the high-power laser in the strong light path based on the weak light transmitted by the spectroscope, and uses Adaptive optics technology implements corrections to optimize the beam quality at the exit of the system. In a high-energy laser system using conventional adaptive optics technology, the spectroscopic image aberration, including its own static aberration and dynamic aberration generated under high-power laser irradiation, is in the detection "blind zone" of the system's wavefront sens...
