Snapshot integral view field imaging full-polarization hyperspectral detection device

Abstract

The invention discloses a snapshot integral view field imaging full-polarization hyperspectral detection device. The snapshot integral view field imaging full-polarization hyperspectral detection device is composed of a front optical lens set, an integral view field unit, a collimating lens set, a full-polarization modulation module, a spectrum light splitting module, an imaging lens set, an area array detector and a data collecting and processing system all of which are sequentially arranged in the direction of incident light. Light emitted by a two-dimensional spatial target sequentially enters the front optical lens set, the integral view field unit, the collimating lens set, the full-polarization modulation module, the spectrum light splitting module and the imaging lens set, and finally reaches the area array detector. The data collecting and processing system controls the area array detector to shoot a frame of image to obtain distribution information of hyperspectral images corresponding to polarized components; then the data collecting and processing system extracts and processes data of the frame of image to obtain information of the spatial morphology, the one-dimensional high spectrum and the full Strokes polarization parameter of the detected two-dimensional spatial target. By means of the snapshot integral view field imaging full-polarization hyperspectral detection device, three-dimensional information of the space, the spectrum and polarization can be obtained in real time.

Problems solved by technology

Literature [8] reported a snapshot polarization hyperspectral imaging technology based on coded aperture technology that can obtain orthogonal linear polarization spectral images. Literature [9] reported a snapshot full polarization hyperspectral imaging technology based on computational tomography. Spectral imaging technology, although the capture of two-dimensional space target information by the two is instantaneous, the algorithm and inversion process of the subsequent polarization spectral information are very complex, heavy, and time-consuming, and it is difficult to realize real-time monitoring on the monitor
