Breath, and when automatically controlled mobile flat rubber belting drives sample continuously to run, then can obtain the continuous one-dimensional image of sample object thing with
And spectral information, or when scanning mirror is being rotated, equally can also obtain continuous the one of object in real time
Tie up image.It is final to obtain one and contain image information and all data can be recorded by computer software in the process
With the three-dimensional data cube of spectral information.By the analysis to data, it can be detected for the quality information of target sample.
Imaging system is the system being combined together by imaging spectrometer and face battle array monochrome cameras completely.Imaging spectrometer
Every time into the picture of a line in target, and light splitting is carried out to the incident light for entering spectrograph slit, light splitting makes each spectral component
A pixel in correspondence detector linear array.Therefore, picture structure of each width from spectrum camera includes a dimension（It is empty
Countershaft）On linear array pixel and in another dimension（Spectrum axle）On spatial distribution（Intensity of the light in spectral element）.So,
By accurate alignment and be fixed together imaging spectrometer and face battle array monochrome cameras, imaging lens and translation mechanism drive sample
Motion or the three-dimensional high-spectral data of object can then be obtained by the rotation of scanning mirror.
Imaging spectrometer uses a new collimation（On axle）Optical configuration and an individual holographic transmission grating.This construction energy
It is enough that very high diffraction efficiency and good line spectrum are provided, and independent incident light polarization is due to that operation is caused on axle
