Abstract

The present invention discloses a sparse target spectrum real-time detection system. The system comprises a pre-mirror, a collimating mirror, a beam splitter prism, a dispersion element, a first imaging mirror, a first detector, a second imaging mirror and a second detector; the pre-mirror images an infinitely far target on the front focal plane of the collimating mirror; light is collimated into parallel light by the collimating mirror; the parallel light is split into two light beams of the same energy through the beam splitter prism; one of the two light beams passes through the dispersion element, and then, dispersed light is imaged on the first detector through the first imaging mirror, and therefore, the target is dispersed into images of different wavelengths, and the images are imaged at different positions; and the other light beam passes through the second imaging mirror and is imaged on the second detector, and the position distribution of the sparse target is recorded. With the system adopted, the problem of the spectrum real-time detection of the sparse target can be solved. The system has high resolution and low error.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a real-time detection system for sparse target spectrum. Background technique [0002] Man-made celestial bodies play an important role in the operation of society, but because these objects are difficult to recycle and become space garbage after being discarded, in some cases, they pose a threat to other normal operating man-made celestial bodies, so it is necessary to detect space objects in real time and identification. [0003] The basic purpose of space target detection is to convert various electromagnetic waves independently generated and passively reflected by space targets into detectable forms to complete the monitoring and identification of space targets. At present, there are mainly long-range warning radars, astronomical telescopes, radio signal monitoring, precision tracking radars, phase control radars, artificial satellite optical cameras, and photoelect...
