Abstract

In this letter, an efficient system of hyperspectral imaging is discussed, which is based on diffractive optic imaging technology. The system is a spectrometer that projects the spectral and spatial information onto a CCD detector. Each spectral image can be obtained by modified demodulation algorithm. The system structure and the basic theory are introduced. A spectrometer system that operates in the visible band is designed. The performance of the system is analyzed and evaluated. The virtual simulation experiment of diffractive optic imaging is established. The simulation of diffractive imaging and spectral demodulation of complex scene have been finished. The experiment PSF is used to demodulate the spectral images. The demodulation output images are almost the same as the initial input image. The validity and feasibility of the basic principle are proved by the simulation experiment result. The experiment system of diffractive optic imaging in visible band is also established in the laboratory. The prototype calibration system is set up. The precise calibration system is needed to be set up in the future. The advantages of diffractive optic imaging spectrometer are no slit and high throughput. The spectrometer can be widely used in remote sensing and other fields.
