Embodiment

[0025] image 3 A schematic diagram of a fully polarized hyperspectral compact and portable imaging device provided by an embodiment of the present invention. Such as figure 1 As shown, the device mainly includes: a front mirror system 2 (field diaphragm), an imaging mirror 3, a linear polarizer array 4 (or including a quarter-wave plate), and a linear gradient filter arranged sequentially on the same optical path. Light sheet array 5 and detector 6;

[0026] The complete polarization hyperspectral imaging device adopts the fusion of complete polarization imaging technology and spectral imaging technology. Its working process is: the incident light 1 enters the primary image surface of the front mirror system 2, and the passing parallel light passes through the imaging mirror 3 and is imaged to On the imaging surface of the detector 6 , that is, in front of the detector, the imaging of the detector is realized by sequentially coupling the linear polarizer array 4 (array of f...

Abstract

The invention discloses a portable compact complete-polarization high-spectral imaging unit comprising a front lens system, an imaging lens, a linear polarizer array, a linear gradient filter array and a detector arranged in order on a same light path. Incoming light enters a primary image surface of the front lens system; parallel beams passing through enter the imaging lens; the light then passes the linear polarizer array and the linear gradient filter array to image the detector. The portable compact complete-polarization high-spectral imaging unit has the advantages of simplicity in processing and adjustment, high stability, high energy utilization rate, good imaging quality, high resolution, compact structure, small size and low production cost.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a compact and portable imaging device for complete polarization hyperspectral imaging. Background technique [0002] The spectral imager can acquire the two-dimensional spatial image and one-dimensional spectral information of the target at the same time. It can not only directly reflect the geometric shape of the measured target, but also provide the physical and chemical properties of the target. It is a detection method combining graphs and spectra. At the same time, it cannot be ignored that the polarization characteristic is a special property of light. Any object in nature will produce polarization in the process of scattering and reflecting light, and this polarization characteristic can reflect the characteristics of the target itself, so Compared with intensity imaging, spectral imaging, infrared radiation imaging and other technologies, polarization imaging det...
