Abstract

The invention discloses a total reflection wide band multi-spectral imaging system which belongs to the technical field of imaging spectroscopy. The system consists of a pre-reflective imaging objective lens, reflective filter imaging, filter control, focal plane array detector imaging, data processing and a system. The total reflection wide band multi-spectral imaging system provided by the invention can simultaneously detect the two-dimensional high spatial resolution image and multi-spectral image of a target in the working range of ultraviolet and near infrared, overcomes the problems of aberration, chromatic aberration, registration and the like of the introduction of a transmission filter of a conventional transmission filter type multi-spectral imaging system, overcomes the problems of slit and low luminous flux and spectral sensitivity in a traditional grating spectral system, and can be widely used in spectral color high-fidelity reproduction, wide-band print quality detection, biomedical multi-spectral imaging, multi-spectral remote sensing and other fields.

Description

technical field [0001] The invention belongs to the technical field of spectral imaging, and in particular relates to a total reflection wide-band multi-spectral imaging system. Background technique [0002] Multi-spectral imaging technology can simultaneously acquire the image and spectral information of the target, and has attracted extensive attention from all over the world. It has a wide range of applications in optical remote sensing, high-precision color fidelity reproduction, artwork identification, medical treatment and public safety. [0003] Existing filter-type multispectral imaging systems use transmission filter systems such as narrow-band interference filters, broadband absorption filters, acousto-optic tunable filters, and liquid crystal tunable filters in the optical path of target image acquisition. , the use of transmission filters will introduce chromatic aberration and aberration to the whole system, so that the positions of the clear imaging planes of ...
