Detected spectra and axial point-spread functions. (a) The detected spectra from the standard scheme (red dotted curve) and the IIS scheme (green solid curve). The blue dashed curve represents the source spectrum. The arrows indicate the locations of the spectrum that were affected by both the camera response and the grating transmission efficiency. (b) The measured axial point-spread functions of the standard scheme (red dotted curve) and the IIS scheme (green solid curve). The depth scales are in air.
