Design, evaluation and applications of a vidicon rapid scanning spectrophotometer
Abstract
The different approaches used in the development of rapid scanning spectrometers were reviewed and grouped into two major classifications, multiplex and dispersion spectrometers. A comparison of the performance characteristics of several rapid scanning instruments has indicated that dispersion spectrometer using electronically scanned array detectors, such as the image dissector tube and vidicon tube, most closely approach the ideal spectrometer for chemical analysis in terms of versatility, photometric accuracy, and speed. A rapid scanning spectrometer using an antimony sulfide vidicon tube was constructed and evaluated. It was found that the antimony sulfide tube responded nonlinearly to varying light levels, but could be used for qualitative studies, such as the detection of intermediate species in chemical reactions. A later version of this instrument using a silicon target vidicon tube has greatly improved performance.
