The grating 2 is positioned between the collimator mirror 1 and the imaging mirror 3; the grating 2 is arranged on a rotation drive device 4 that can drive the grating 2 to rotate. Therefore, the utility model is able to realize high spectrum resolution rate.
Description
One, technical field
The utility model relates to a kind of imaging spectrometer, the rotatable chromatography type of especially a kind of grating imaging spectrometer.
Two, background technology
The main function of chromatography type imaging spectrometer is to gather the spectrum picture that is called ' spectroscopic data cube ' of scenery.Its structure be to use pre-objective with Scenery Imaging on field stop, the picture of scenery through behind the diaphragm through collimating mirror, on focus planardetector, become to have the chromatic dispersion picture through optical grating diffraction and imaging mirror, wherein diaphragm is positioned at the front focus position of collimating mirror, focus planardetector is positioned on the focus of imaging mirror, through obtaining the spectral radiance data cube of scenery after computer data acquiring and the spectrum inverting image reconstruction software processes.Its major defect is to be subjected to restrictions such as aftertreatment computing power and focal plane resolution, and spectral resolution is low.
