摘要	Optical distortion is a kind of ubiquitous problem in optical system, although it has little effect on the clarity of the image, it has a bad effect on the precision of the imaging geometrical position, especially in the optical system with large field of view, and it will be increased largely with increasing the view field. In the LASIS(Large Aperture Static Imaging Spectrometer) system, if the optical system has distortion, it may lead to inadequate sampling, which means that it couldn't satisfy the Nyquist sampling theorem, causing the recovery spectrum distortion. Because the larger the distortion, the lower the registration precision, it's very hard to correct the distortion effect, thus, it is useful to analyze the influence of optical system distortion on the image quality. An optical distortion model is developed in the paper to evaluate the optical design, the distortion data is calculated from the optical design software and the influence of optical system distortion on the data acquired by LASIS is analyzed.
