Satellite-borne calibration light source device

Abstract

The invention belongs to the technical field of space optical calibration, and relates to a satellite-borne calibration light source device which comprises a Y-shaped optical fiber (5), an upper protective shell (8), an upper calibration spectral line mechanism, an adapter plate (13), a lower protective shell (9) and a lower calibration spectral line mechanism; one end of the Y-shaped optical fiber (5) is a converged optical fiber bundle end, the other end of the Y-shaped optical fiber (5) is an optical fiber bundle split end; the optical fiber bundle split end comprises a first optical fiberbundle tube (29) and a second optical fiber bundle tube (30); the first optical fiber bundle tube (29) is correspondingly inserted into the upper calibration spectral line mechanism mounted in the upper protective shell (8) through a tube sleeve (33) arranged at the end part of the first optical fiber bundle tube (29); the second optical fiber bundle tube (30) is correspondingly inserted into thelower calibration spectral line mechanism mounted in the lower protective shell (9) through a tube sleeve (33) arranged at the end part of the second optical fiber bundle tube (30); and the upper protective shell (8) and the lower protective shell (9) are separated by the adapter plate (13).

Description

technical field [0001] The invention belongs to the technical field of space optical calibration, and in particular relates to a spaceborne calibration light source device. Background technique [0002] A variety of calibration light sources are used for on-orbit calibration of space optical instruments such as cameras and spectrometers, among which the spectral line lamp is one of the calibration light source devices. The spectral line lamp is usually a cylindrical glass lamp tube, which is easily damaged by mechanical vibration during rocket launch. In order to improve the shock resistance of the existing calibration light source of the spaceborne spectral line lamp, the size of the light source is reduced, resulting in low energy of the light source. In addition, the existing calibration light source is usually a single-line lamp, however, the single-line lamp is usually a large-scale spectral line lamp, which has poor shock resistance and narrow spectral coverage.
