Measurement of relative spectral sensitivity distributions of photoelectric receivers.
An apparatus is described for the fully automatic measurement of the relative spectral sensitivity distributions of photoelectric receivers. A substitution method is used in which, after calibration of an auxiliary photomultiplier against a reference thermopile, the sample receiver is mounted in the position formerly occupied by the thermopile. Precision and accuracy of the measurements are discussed.
