Claim 8:
9. The curved-slit imaging spectrometer of claim 7, wherein the shape of the spectral line generated on the focal plane detector is consistent with the shape of the curved slit, this spectral line is transformed into a straight spectral line corresponding to pixels in object plane through a mapping transformation algorithm, and this mapping consists in transforming the equation for the arced spectral line y1=rs−√{square root over (rs2−x12)} into the equation for the straight spectral line, {
