Available in PDF, EPUB and Kindle. Book excerpt: A description of the 36-in. Navy Searchlight Source of thermal radiation shows that this source will provide an irradiance at the exposure plane of 90 cal/cm-2/sec which can be delivered in either of two types of pulses, a triangular sweep pulse or a square wave pulse. The photoelectric method of carbon position control, the method of monitoring the beam during an exposure and the spectral distribution of the radiant energy are shown. The Mitchell Source, known to the motion picture industry as the "Mitchell Process Projector" and its modifications for the study of the effects of thermal radiation on materials is described. The methods of making neutral attenuators of ground glass plates and the production of a variable type pulse mechanism are also given. The pertinent facts relating to various parameters of the two sources discussed in this report are presented in a table.
