Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0037] The invention provides a space-borne small-scale lightweight Dyson hyperspectral imager system. The system realizes the separation of the object plane and the image plane of the optical system through the optical optimization design of the Dyson prism and the rear mirror assembly, and avoids the separation between the object plane and the image plane. The coincidence leads to the disadvantage of difficult layout of the optical support structure, which is easy for engineering development.

[0038] Such as figure 1 with figure 2 As shown, the spaceborne small-scale lightweight Dyson hyperspectral imager system of the present invention includes a front telescope group 1, a Dyson prism mirror group 2, a rear mirror assembly 3, an electronic focal plane assembly 4, a box b...

Abstract

The invention provides a satellite-borne small-sized light-weight Dyson hyperspectral imager system, and solves the problem that an existing Dyson prototype spectrometer is difficult to carry out structural layout and engineering development due to the fact that the structure is too compact. The system comprises a box body, a front telescope group, a Dyson prism group, a rear lens assembly, an electronic focal plane assembly and an accurate measurement lens assembly. Incident light enters through the front telescope group, sequentially passes through the Dyson prism group and the rear mirror assembly, is reflected by the rear mirror assembly to realize light path multiplexing, and then passes through the rear mirror assembly and the Dyson prism group to be imaged on the electronic focal plane assembly. The system can realize separation of an object plane and an image plane, and is easy to realize structural layout and engineering development.

Description

technical field [0001] The invention belongs to the field of space-borne hyperspectral imaging, and in particular relates to a space-borne small and lightweight Dyson hyperspectral imager system. Background technique [0002] The spectral imager can realize spectral imaging, and can detect two-dimensional spatial information and one-dimensional spectral information at the same time. It has the functions of qualitative measurement and quantitative analysis at the same time as timing and positioning measurement, so it can be applied in material detection, target identification, composition Analysis, process monitoring and many other fields. Compared with ground-based spectrometers and airborne spectrometers, spaceborne hyperspectral imagers can achieve normalized, wide-ranging, and high revisit rate detection, and are widely used in military, agriculture, oceanography, geography and other fields. [0003] With the continuous development of the space platform cube star and mic...
