Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] As shown in 1, a filter-type spectrometer with adjustable linear dispersion rate includes: a light source 1, a converging lens 2, a slit 3, a collimating lens 4, a linear gradient filter 5, and a linear array CCD detector 6.

[0023] Light source 1 sends light beams into converging lens 2, converging lens 2 converges the light beams to slit 3, slit 3 is located at the focus position of collimating lens 4, and the light beam coming out from slit 3 becomes Parallel light is incident on the surface of the linear gradient filter 5, and the spectral information obtained after being split by the linear gradient filter 5 is detected by the linear array CCD detector 6, and then transmitted to the computer correlation analysis software for analysis.

[0024] Such as figure 2 As shown, the thickness of the resonant cavity layer of the linear gradient fil...

Abstract

The invention relates to a filter spectrometer with adjustable linear dispersion rate. Light beams emitted by a light source enter a converging lens. The converging lens converges the light beams to aslit in the focus position of a collimating lens. The light beams going out of the slit are changed into parallel light after passing through the collimating lens, and the parallel light is incidenton the surface of a linear gradient filter. A light-splitting spectrum is detected by a linear array CCD detector according to spectrum information obtained through light splitting by the linear gradient filter, and is transmitted to a computer for processing. The linear array CCD detector is fixed on a rotary adjustable bracket. With the direction in which the resonant cavity layer of the filterchanges thickness fastest as a reference direction, the linear array CCD detector is rotated in such a way that there is an included angle between the length direction of the detector and the reference direction. Then, the transmitted light of the filter is detected, and the dispersion rate can be changed. The linear array CCD detector can move in a two-dimensional direction to measure light within different wavelength ranges. The filter spectrometer has the advantages of simple structure, convenience of use and adjustable linear dispersion rate.

Description

technical field [0001] The invention relates to a filter-type spectrometer with adjustable linear dispersion rate, belonging to the technical field of adjustable filter-type spectrometers. Background technique [0002] A spectrometer is an optical instrument that decomposes polychromatic light into a spectrum. The spectrometer can be used to obtain the spatial spectral information of an object and realize the spatial detection of the target. Spectrometers have very important applications in many fields such as aerospace, resource surveying, environmental monitoring, and medical imaging. [0003] Spectrometers can be roughly divided into dispersion type, interference type, and filter type according to the principle of light separation. The spectrometer based on the principle of dispersion mainly uses dispersion elements (such as prisms, gratings, etc.) to disperse and split the light beam; the spectrometer based on the principle of interference uses the Michelson interferenc...
