Abstract

The invention discloses a miniaturized linear variable filter type imaging spectrometer with high integration level, which comprises a linear variable filter (LVF) and a detector, wherein the two ends of the LVF are provided with a support wing respectively, the support wings are arranged on a base, one surfaces of the support wings and a non-coating surface of the LVF are positioned on the same plane, a coating surface of the LVF is close to a photosensitive surface of the detector and a certain distance exists from the photosensitive surface to the coating surface. Compared with the conventional imaging spectrometer, the imaging spectrometer disclosed by the technical scheme has the following advantages that 1, the integration level is high, the structure is stable, miniaturization is easy to realize, and the imaging spectrometer can be installed on equipment, such as a moving platform and an aerospace vehicle; 2, the lead time is short, the cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a highly integrated miniaturized linear gradient filter imaging spectrometer. Background technique [0002] The spectral imaging technology combines the camera with the spectral instrument, and can obtain the spectral image information of the target two-dimensional space and one-dimensional spectral map, which can directly reflect the spectral characteristics and geometric shape information of the target, and realize the comprehensive detection and perception of the target characteristics and identification. Applying it to the fields of aerospace remote sensing, precision agriculture, food safety, environmental monitoring and resource detection has advantages that a single camera or spectrometer cannot match. [0003] According to different spectroscopic principles, imaging spectrometers are generally divided into three types: dispersion type, interference type and filte...
