Abstract

The invention discloses a sun-image-movement-based atmosphere turbulence measurement apparatus and a method thereof. The apparatus comprises a sun image capturing component array, an automatic guide adapter, a solar orientation program, a synchronous controller, a daytime atmospheric turbulence measurement procedure and an equatorial telescope. The sun image capturing component array consists of two or three sets of sun image capturing components formed by band-pass filters, small telescopes, magnification lens combination units and cameras. The solar orientation program controls the equatorial telescope to complete sun position correction and automatic sun tracking by the automatic guide adapter. The daytime atmospheric turbulence measurement procedure controls the sun image capturing component array to collect a sun image synchronously by the synchronous controller to obtain an overall atmosphere seeing and a medium-resolution atmosphere turbulence profile. According to the invention, the sun can be tracked automatically; the overall sun surface can be observed; field installation and debugging can be realized conveniently; and the long-term operation demand can be satisfied.

Description

technical field [0001] The invention relates to an atmospheric turbulence measurement device and a solar image monitoring method based on solar image movement, and belongs to the technical field of atmospheric optics. Background technique [0002] High-resolution observations of solar active regions are extremely important for the development of solar physics. Large-aperture ground-based solar telescopes need to be equipped with multi-layer conjugate adaptive optics systems to expand their observation fields. However, the design and optimization of the solar multilayer conjugate adaptive optics system needs to measure the long-term distribution of daytime atmospheric turbulence. [0003] At present, the principles of daytime atmospheric turbulence measurement devices applied to solar stations mainly include: measuring the jitter of the sun's edge or surface targets, solar flare or solar surface target flare. For example: the solar edge image motion monitor can obtain the o...
