“…One-dimensional image processors have been successfully applied to astronomical studies (13), atomic emission (14-16), atomic absorption (17), molecular absorption (18), and picosecond flash photolysis (19). Two-dimensional image processors have been coupled with echelle spectrometers for multielement analysis (20,21) and with fluorometers for obtaining simultaneous excitation and emission spectra (22). Not all spectrometric techniques are equally suited for spatial imaging.…”
