Problems solved by technology

[0002] At present, spectral analysis instruments are widely used in scientific experiments, industrial and agricultural production, national defense and other fields. However, most spectral analysis instruments are bulky and complex in structure. It can flexibly obtain images of various spatial dimensions of the object and perform spectral analysis. Based on this, a miniature imaging spectrometer combining imaging technology and spectral analysis technology has emerged, which has the advantages of small size, light weight, and flexible acquisition of more objects. Features of Spatial Dimension Information

[0003] However, the existing miniature spectral imaging system uses a spectroscopic filter, a prism or a transmission grating as a spectroscopic element to filter, and then obtains an image of a specific wavelength on the CCD image sensor. After the image obtained by this method is subjected to spectral analysis, The obtained spectral image is relatively scattered and cannot obtain complete and wide-range spectral characteristics. Moreover, due to the mechanical vibration in the process of obtaining the image, it is easy to affect the accuracy of the spectral image formed after spectral analysis based on the image.
