Abstract

The invention discloses an imaging method and an imaging spectrometer based on Wollaston prism light splitting. The imaging method based on the Wollaston prism light splitting comprises the following steps: changing a light polarization direction of light by a first polarizing film and carrying out light splitting by a first Wollaston prism to obtain two bundles of the light; changing the light polarization direction of the light by an nth polarizing film and carrying out the light splitting by an nth Wollaston prism to obtain 2n bundles of the light, wherein n is equal to 2 or 3; penetrating through an imaging mirror and compensating an optical path of the 2n bundles of the light by an imaging mirror and imaging on a detector. The imaging spectrometer based on the Wollaston prism light splitting has a coaxial optical path, high stability, high energy utilization rate and good imaging quality, and is applicable to the civil use fields of biomedicines, food rapid detection and the like.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an imaging method and imaging spectrometer based on Wollaston prism spectroscopy. Background technique [0002] Imaging spectroscopy technology integrates optics, spectroscopy, precision machinery, electronic technology and computer technology, and is an innovation based on multidisciplinary integration. The imaging spectrometer is an optical remote sensing instrument that can obtain two-dimensional spatial information and one-dimensional spectral information of the measured target. The image data obtained is called "Data Cube", which is a new type of multi-dimensional information access technology. Because of its rich spectral data information, it has been widely used in aerospace remote sensing, military applications, scientific experiments, astronomical observations, environmental monitoring, disaster assessment, resource surveying, biomedicine and other fields.
