Near-Field Mechanism Research on Hyperspectral Image Plane Interferometric Imaging
The technology of image plane interferometric imaging has the advantages of high luminous flux, high target resolution and high spectral resolution. It is mainly applied in remote sensing imaging field. In order to achieve the near-field target detection, the theory of near-field image plane interferometric imaging is analyzed. The factors affecting image quality is studied and the physical expressions of optical path difference and the minimum detection are described. The modulation influencing factors of near-field image plane interferometric fringe are studied and the calculation method of modulation is deduced. The impact of the interferometric fringe modulation on the signal-to-noise ratio and the accuracy of the recovery spectrum is analyzed. For improving the modulation of near-field interferometric imaging and the image quality, a re-imaging interferometric system is set up. Experimental device of imaging plane interferometric spectrometer is set up to detect the near-field targets and the experimental interferometric images are analyzed. A re-imaging experimental device is set up and we get a series of near-field target interferometric images with high modulation.
