Multi-channel multi-target ultra-optical spectrum imaging method and system based on digital micro lens device

Abstract

The invention discloses a multichannel multiobjective hyper-spectral imaging method based on numerical microscopes, characterized in that, an object is imaged on a slit plane, an emergent light is collimate into a parallel light, split into ultraviolet light, infrared light and visible light, which are diffracted into the dispersion through the respective split grating diffraction, then is focused on the corresponding numerical microscope; the turning state of the numerical microscope is controlled by the computer, and the emergent light of the on-state is projected on the detector, used for image and post-treatment through the data acquisition treatment. The device is arranged with a multi-agglutination prism of the dichroism filter, and the dispersion of the ultraviolet light, the infrared light and the visible light is realized. The method realizes the image information acquisition of the triband of infrared light, visible light and ultraviolet light, solves the problems that the spectrum imaging data are too large without affecting the spectrographic detection quality of the target area, and is in favor of realizing the multiobjective identification and the real-time track.

Description

technical field [0001] The invention relates to a hyperspectral imaging instrument, in particular to a multi-channel hyperspectral imaging system which adopts a digital micromirror device and can be used for multi-target identification and tracking. Background technique [0002] The spectral imaging instrument is an optical imaging instrument that can realize "map-spectrum integration". Hyperspectral imaging usually refers to spectral imaging technology with a number of spectral bands in the range of 100 to 400. It is currently used in remote sensing observation fields such as environmental monitoring, military investigation, forest fire prevention, crop yield estimation, and pest monitoring, as well as in PCB inspection, biochips and DNA chips. There are very important applications in the field of microscopic detection such as detection.

Problems solved by technology

[0003] An important factor restricting the development of multispectral imaging technology is that the data of hyperspectral imaging is too large

Especially for the remote sensing hyperspectral imaging technology that is currently the most widely used, as a satellite payload, it is impossible for the remote sensor to be equipped with a large-capacity data storage device, and the existing data transmission rate to the ground is difficult to achieve an ideal value, which is a problem for satellites. The hardware equipment and software methods of data compression on remote sensing devices have put forward a great challenge

Multi-target hyperspectral imaging can identify and track military targets, civilian targets, and micro-chip targets. The background of the target is mostly useless information, which takes up a lot of data and brings great difficulties to target identification and tracking.

[0004] Limited by the corresponding detection range of spectroscopic devices and detectors, traditional spectral imaging systems are generally limited to only one waveband (mostly visible or near-infrared)
