Imaging Spectrometer Based on Filter Effect and High Spatial Resolution Spectral Imaging Method

Abstract

The invention discloses an imaging spectrometer based on filtering effects and a high spatial resolution spectral imaging method. The imaging spectrometer includes a front-end device, a filter device, a collimation device, an array detection chip, a control device, and a data calculation and analysis system; The imaging spectrometer disclosed in the invention controls the filter device through the control device. The light intensity detected by the same pixel element under different control conditions is different from each other. Substituting it into the matrix equation to calculate the spectrum can output more control parameters through the control device to realize Higher spectral resolution; due to the large number of pixels on the array detection chip, each pixel can be used as a separate detector for different subunit areas of the imaging area to be measured by dividing the target area Spectral measurements are performed, so the spatial resolution of spectral imaging is high. Compared with the traditional imaging spectrometer, the imaging spectrometer disclosed in the present invention has smaller volume, lower cost and higher performance.

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
