Analyzer for Photographically Recorded Time-resolved Spectra

Volume 28, Number 1 (Feb. 1974) Page 75-78

Hamm, F.M.; Walters, P.E.


Time-resolved spectra recorded photographically have been used frequently by various workers, time usually being displayed along the length of the recorded lines. Manual photometry of the plate, however, becomes rather tedious the more advantage one wants to take of its inherent information capacity. Maximum densities or, for that matter, minimum transmission must be measured at a great number of points along each line, i.e., 50 to 100 points.
