Abstract
Here two imaging spectrometers, based on a different prism-grating-prism (PGP) dispersing component, are designed and presented. One works at the visible near infrared (VNIR) waveband from 400nm to 1000nm with 1.7nm/pixel spectral resolution, 85mm track length. As for the other, its spectral coverage, spectral resolution, and track length are the short wavelength infrared (SWIR) waveband from 900nm to 1700nm, 3nm/pixel, and 108mm, respectively. Both of the imaging spectrometers have advantages of fast speed (F/2.0), wide spectral range, low distortion, low cost, even relative illumination, and compactness made them ideally suited for hyperspectral imaging remote sensing. Either of them gains the preferable imaging quality.
