Light and small interference imaging spectrum full-polarized detection device

Abstract

The invention discloses a light and small interference imaging spectrum full-polarized detection device comprising a preposed optics looking-out system, a static full-light modulation module, an angle shearing static interference imaging spectrometer, an imaging mirror set and a detector which are coaxially and successively arranged in sequence, wherein the detector is connected with a signal obtaining and processing system; after being collected, collimated and performed with stray light elimination by the preposed optics looking-out system, irradiation light emitted by a target source enters the static full-light modulation module; after passing through an angle shearing birefringent crystal set, one beam of modulation line polarized light is sheared into polarization light at an angle; after passing through an analyzer, the polarization light is divided into two beams of line polarized lights; the two beams of the line polarized lights are gathered in the detector after passing through the imaging mirror set; and the received signal is processed by the signal obtaining and processing system to obtain a target image, hyperspectral information and full-polarized information. The invention has the characteristics of compact and simple structure, no moving components and large luminous flux, can obtain a target two-dimensional space image, one-dimensional hyperspectral information and integral polarization information in one time.

Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to a three-in-one light and small interference imaging spectrum full polarization detection device capable of simultaneously obtaining target two-dimensional intensity, Fourier transform interference spectrum and full polarization characteristics. Background technique [0002] The light emitted by the light source irradiates any target on the earth's surface and in the atmosphere. During the process of radiation, reflection, transmission and scattering of light waves, it will cause changes in the intensity of light waves, spectral radiation characteristics and polarization states, and the camera (imaging imaging) has been developed independently. Instruments), spectrometers, and polarimeters are three types of optical characteristic detection instruments, which can respectively obtain the two-dimensional spatial information of the target, the material structure and chemic...
