Abstract
This study designed a large aperture infrared diffraction system that utilizes Schupmann's achromatic theory to achieve wavelength tunable high-resolution imaging. The impact of stitching error on imaging quality was analyzed based on geometric optics, and simulation analysis was conducted on stitching error based on wavefront aberration. The results indicate that the system has reached the diffraction limit of imaging quality in the design band, and both wavefront aberration and distortion are within acceptable ranges. Splicing error analysis shows that translation error has a significant impact on imaging quality, while edge mismatch error and tilt error have a smaller impact. This system has the characteristics of lightweight and low cost, and is suitable for various space observation tasks.
