Abstract

The invention discloses an integrated airborne large visual field hyperspectral imaging system based on optical fibers and Fery prisms. The integrated airborne large visual field hyperspectral imaging system is characterized by comprising a front-mounted lens, a mechanical slit, a one-to-N area array optical fiber image transmitting beam, N spectrographs and N detectors, wherein the spectrographs are Offner relay imaging systems containing curved prisms, namely the Fery prisms; the front-mounted lens is used for imaging a far target object to a one-time image surface; the mechanical slit is arranged at the one-time image surface, and plays a role of a field diaphragm; the incidence end of the one-to-N area array optical fiber image transmitting beam is tightly coupled with the mechanical slit; one spectrograph and one detector are sequentially connected to each emitting end. Compared with a current common visual field external splicing mode, the system disclosed by the invention is compact, light and simple in structure.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to an integrated airborne large-field-of-view hyperspectral imaging system based on an optical fiber and a Féry prism. Background technique [0002] With the rapid development of imaging spectrometers, airborne imaging spectrometers will have a large field of view and wide coverage, high spatial and spectral resolution, and high detection sensitivity, integrating new principles, new methods, new technologies and new instruments, suitable for Space earth observation and deep space exploration, land surface and ocean and atmospheric detection and monitoring; extremely small individual size and high sensitivity of targets with cluster distribution characteristics, and research fields such as biology, medicine and life sciences. [0003] An important feature of the airborne imaging spectrometer is the large field of view. Field of view is an important indicator of remote sensi...
