Reply to comments on "Absolute linearity measurements on a PbS detector in the infrared".
Some issues on the method used by Zhang et al. [Appl. Spectrosc. 51, 576 (1997)] to correct for the nonlinearity of a HgCdTe detector in Fourier transform spectrometry measurements are discussed in response to comments by Zhang. Other problems that must be taken into consideration before the effects of detector nonlinearity of HgCdTe detectors are fully accounted for in FT spectrometry are highlighted.
