Abstract In the present paper, we simulated the system optical magnification error’s influence on the quality of reconstructed image, analyzed the variant of the coded aperture with different optical magnification, then proposed an accurate curve of image quality and optical magnification in 128×128 code template, which provide important references for the design and development of push-broom coded aperture spectrometer.
