Abstract

Coded aperture spectroscopy allows for sources of large field to be efficiently coupled into dispersive spectrometers by replacing the traditional input slit with a patterned mask. Spectral calibration is requisite for spectroscopy to obtain the spectrum information exactly. In this paper, we described the spectral calibration’s principle and methods of coded aperture spectral imaging, and then gave the results of the experiment using a monochromatic extended source, at last we tested the accuracy of spectral calibration. The results indicate that this method can calibrate the coded aperture imaging spectrometer with high accuracy.
