Embodiment

[0028] Embodiment: A kind of novel hyperspectral video imager, such as figure 1 As shown, it includes a lens 1 , a beam splitter 3 , a micromirror array 6 , a beam splitting prism 7 , a collimation system 2 , a first converging system 4 , a second converging system 8 , a grayscale camera 9 and a color camera 5 . The collimation system 2 is located between the lens 1 and the beam splitter 3 , and is used for receiving the light of the object to be measured transmitted by the lens 1 and sending the light of the object to be measured to the beam splitter 3 . The beam splitter 3 is used to split the incident light into two beams, one beam of light enters the color camera 5 after being converged by the first converging system 4, and the other beam of light is irradiated on the micromirror array 6 and dispersed by the beam splitting prism 7, The dispersed light converges to the gray scale camera 9 through the second converging system 8 .

Abstract

The invention, which belongs to the technical field of the imaging spectrum, discloses a novel hyperspectral video imager comprising a lens, a beam splitter, a micro-mirror array, a beam splitting prism, a collimating system, a first convergence system, a second convergence system, a grayscale camera, and a colored camera. The collimating system arranged between the lens and the beam splitter is used for receiving a to-be-tested surface feature light transmitted by the lens and transmitting the to-be-tested surface feature light to the beam splitter. The beam splitter is used for splitting incident light into two beams; one beam of light is converged by the first convergence system and then enters the colored camera and the other beam of light irradiates the micro-mirror array; the beam splitting prism carries out chromatic dispersion; and the light after chromatic dispersion is converged to the grayscale camera by the second convergence system. According to the invention, a problem ofpoor real-time performance of measurement by the traditional imaging spectrometer is solved; the real-time performance is enhanced; spectral information of each pixel position can be collected accurately; and all spatial information and spectral information of the to-be-tested surface feature can be obtained quickly.

Description

technical field [0001] The invention relates to the technical field of imaging spectrum, more specifically, it relates to a novel hyperspectral video imager. Background technique [0002] The imaging spectrometer can simultaneously obtain the spatial image information and spectral information of the ground object to be measured. This kind of spectral detection method that can be positioned has important and wide applications in many fields. [0003] Traditional imaging spectrometers can be simply divided into scanning type and staring type (non-scanning type) according to the data acquisition method. Scanning imaging spectrometers use line array or area array detectors to obtain image information and spectral information of one or a row of spatial points at one time, and then obtain a larger range of spatial image information (and spectral information) through scanning. The staring imaging spectrometer does not need to scan, and uses the area array detector to image a large...
