Abstract

A spectral surface resetting device of a hyperspectral imager relates to the field of the precisely mechanical structures of a hyperspectral imager, a high spectrometer and a spectrometer, and solves the problems that the resetting process is complicated and the image surface position of the hyperspectral imager cannot be accurately measured because the resetting device of the existing charge coupled device (CCD) imaging system directly carries out the imaging regulation on the CCD focal plane. The device comprises a baseplate and a reticle component, wherein the reticle component comprises areticle seat, a positioning frame, a reticle, a screw of the positioning frame, an elastic pressing plate of the reticle, an adjustable pad of the reticle seat and a fixed screw of the reticle seat, the adjustable pad of the reticle seat is arranged between the baseplate and the reticle seat, the reticle seat is fixed with the positioning frame through the screw of the positioning frame, and the elastic pressing plate of the reticle and the reticle are sequentially arranged in the positioning frame; and the reticle component is fixed with the baseplate through the fixed screw of the reticle seat. The device is convenient to use, the frequent operations during resetting a CCD focal surface component are reduced, and the product quality and reliability are improved simultaneously.

Description

technical field [0001] The invention relates to the field of hyperspectral imager, hyperspectral instrument, and spectrometer precision mechanical structure in an optical imaging system, in particular to a spectrum plane or focal plane adjusting device of a hyperspectral imager. Background technique [0002] At present, the adjustment device of the existing CCD imaging system directly adjusts the CCD focal plane for imaging, and the adjustment process is time-consuming and laborious. Or use a flat ground glass to observe the image plane position of the hyperspectral imager, but this method cannot accurately position the CCD photosensitive position along the meridional and sagittal directions, nor can it accurately determine the position along the focal plane focal depth direction. Therefore, it is also impossible to use a microscope to accurately calibrate the spectral plane of the spectrometer or the position along the focal plane, and it is impossible to quickly and accura...
