Paper Abstract

A conventional grating spectrometer has been modified to incorporate electronic spectral scanning through the use of a special purpose image dissector photomultiplier tube. The control of the deflection coils is synchronized with data storage location in a 1024 memory analyser thus ensuring precise wavelength repeatability during successive spectral scans. The control logic enables three selectable wavelengths to be sampled at repetition rates of up to 30 samples per second. The system has been applied to several problems encountered in aeronomical research where the spectrum under study is of varying intensity or where precise wavelength repeatability is required.
