Abstract: A signal obtained by an analytical instrument is converted into a light and shade spectrum by an electron exposure unit, the said light and shade spectrum then being formed into a hologram. Unknown samples are qualitatively and quantitatively analyzed by correlating the hologram formed by a given unknown sample with the hologram of a known sample. Further, if the output signal from an interference spectrometer is fed into the exposure unit, a light and shade spectrum in the form of a hologram is produced. By applying Fraunhofer diffraction, Fourier transformed spectrum in reverse corresponding to a wave number is derived from the said hologram.
