Filtering effect based imaging spectrometer and high-spatial-resolution spectrum imaging method

Abstract

The invention discloses a filtering effect based imaging spectrometer and a high-spatial-resolution spectrum imaging method. The imaging spectrometer comprises a prepositioned device, a filtering device, a collimation device, an array type detection chip, a control device and a data calculation and analysis system. The imaging spectrometer controls the filtering device via the control device, thedetected light intensity of the same pixel element under different control conditions is different, and is substituted into a matrix equation to calculate the spectrum, and the control device outputsmore control parameters to realize high spectral resolution; and the array type detection chip includes relatively more pixel elements, a target to be detected is divided into areas, each pixel element can serve as an independent detector to carry out spectrum measurement on different subunit areas in the imaging area to be detected, and thus, the spatial resolution of spectrum imaging is higher.Compared with a traditional imaging spectrometer, the imaging spectrum of the invention is smaller in size, lower in cost and higher in performance.

Description

technical field [0001] The invention relates to an imaging spectrometer and a spectral imaging method for obtaining rich information of spatial dimension and spectral dimension, which can be used in the technical field of remote sensing and imaging with high spatial resolution and high spectral resolution. Background technique [0002] The imaging spectrometer can obtain a data cube composed of two-dimensional spatial information and one-dimensional spectral information of the measured target. With the continuous development of hyperspectral imaging technology, spaceborne hyperspectral imaging will be applied in more and more fields, with broad prospects for development.

Problems solved by technology

If the existing imaging spectrometer product is used, when the artificial satellite performs remote sensing monitoring on the ground, since the imaging spectrometer on the artificial satellite is far away from the ground, a tiny image point on the ground captured by an ordinary camera may be an important target to be monitored. Image points may not be monitored by commercial imaging spectrometers with insufficient spatial resolution
