Due to the recent advent of diode arrays and their subsequent use in radiometers, there has been some discussion about the accuracy of using diode array radiometry in the measurement of pulsed and flash sources. In order to determine whether or not diode array radiometers are accurate instruments for measuring these sources, a Tracor Northern TN-1710 radiometer, which uses a diode array, and a conventional, single channel Optronic 730A radiometer were used to measure three sources. These three sources consisted of a 45 watt tungsten-halogen lamp pulsed with an optical chopper.- a cathode ray tube (CRT) and a xenon flash. It was determined that there was no significant difference between the measurements taken with either system as long as the intensity of the source was high enough to overcome the inherent noise associated with a diode array.
