Embodiment 1

[0042] See attached figure 1 , is the spectral calibration device proposed by the present invention, mainly composed of three parts, 101 is a uniform lighting panel, 102 is an optical fiber, and 103 is an excitation light source module.

[0043] The structure of the lighting panel is as figure 2 As shown, the lower layer is a light guide plate, which is composed of a light inlet 1011A, a light guide strip 1011B, and a light uniform plate 1011C. The bottom surface of 1011C is a tetrahedral microstructure, and the prism plate 1012 is placed on the top of the uniform light plate 1011C. The light inlet 1011A guides the light transmitted by the optical fiber into the light guide strip 1011B; the light guide strip 1011B is used to reflect the light entering from 1011A to the light uniform plate 1011C. In order to improve the utilization rate of light, the side of the light guide strip is made with a certain inclination angle , and coated with a wide-band high-reflection film; the...

Abstract

The invention discloses a portable spectral calibration device and a spectral calibration method of the portable spectral calibration device. An excitation light source module of the calibration device comprises a light source, a battery, an oscillating circuit and a light collecting element. A lighting panel is of a two-layer structure comprising a light guide plate and a prism plate, the prism plate is arranged on the upper layer, the light guide plate is arranged on the lower layer, the light guide plate comprises a light inlet, a light guide bar and a light uniformizing plate, the bottom face of the light uniformizing plate is composed of a plurality of single tetrahedrons, and the prism plate is arranged on the upper portion of the light uniformizing plate. Lasers emitted by the excitation light source module are transmitted to the light inlet of the lighting panel through an optical fiber to enter the light guide bar. The lighting panel is of the two-layer structure, and thus the divergence-angle-controlled light source with certain uniformity and large area is provided; the tetrahedron microstructures are arranged at the bottom of the light guide plate, and thus the calibration light source can achieve certain uniformity; the prism plate is adopted for controlling the angle of divergence of light, and thus the light energy utilization rate can be increased. The spectral calibration device is small in size and light in weight and can be conveniently used for calibrating a field imaging spectrometer.

Description

technical field [0001] The invention relates to a spectrum calibration device, in particular to a portable spectrum calibration device suitable for the field. Background technique [0002] At present, imaging spectrometers have been widely used in agricultural production management, resource investigation, biomedicine and other fields. However, with the development of optics, electronics, computers and other technologies, the spectral resolution of imaging spectrometers can be made very high. The spectrometer is calibrated before use to improve the reliability of the spectral data. At present, laboratory spectral calibration equipment is based on monochromator wavelength scanning and spectral lamps. Calibration equipment and calibration methods based on monochromators are complicated and difficult to use in the field, airborne or spaceborne, and spectral lamps are difficult to provide. Uniform and large-aperture systematic illumination. At present, the spectral calibratio...
