Solar simulation device capable of distinguishing photosphere and corona

Abstract

The invention discloses a solar simulation device capable of distinguishing the photosphere and the corona, belongs to the technical field of corona observation, and aims to solve the problems that an existing solar simulation device can not satisfy the characteristics of high luminous intensity and independent illumination of the photosphere and the corona. The device comprises an illuminating system, a photosphere imaging system and a collimation system. The photosphere imaging system comprises ground glass, a first metal plate, a first lens, a second lens, a damping piece and a second metal plate. A first light-shielding plate and a second light-shielding plate are arranged inside a light-shielding system. The first metal plate is arranged on an object space focal face of the first lens, the second metal plate is arranged on an image space focal face of the second lens, and the second metal plate is arranged on an object space focal face of the collimation system. Light emitted by the illuminating system is homogenized by the ground glass, the homogenized light successively reaches to the first metal plate and the first lens in an incident mode, the homogenized light forms parallel light after passing through the first lens, the parallel light converges to the damping piece through the second lens, the light enters the collimation system after penetrating through the damping piece, and simulated sunlight is output from the collimation system.

Description

technical field [0001] The invention belongs to the field of corona observation, and is applied in a coronagraph experiment process for coronal observation in a laboratory, and in particular relates to a solar simulation device capable of distinguishing the photosphere and the corona. Background technique [0002] At present, in the field of imaging instrument development for coronal observation, laboratory simulation experiments are required before the instrument is applied to actual observation, and the solar simulator has become an extremely important prerequisite. It should not only reflect the sun's strong light and similar broad-spectrum characteristics, but also reflect the radiant energy gap between the photosphere and the corona and the characteristics of independent light emission. Although there are solar simulators with excellent performance in the prior art, they have many shortcomings such as high cost, large volume, and large required experimental site. There...
