THE DISTRIBUTIONS OF RADIATION FROM A RADIATING SPHERE AND DISC AT THE FOCUS OF AN ELLIPTIC MIRROR
Thomas, P.H. and Karas, G.C., 1958. THE DISTRIBUTIONS OF RADIATION FROM A RADIATING SPHERE AND DISC AT THE FOCUS OF AN ELLIPTIC MIRROR. Fire Research Notes339
The distribution of radiation at the focus of an elliptional mirror from a sphere or disc at the other focus is calculated and the result compared with the measurement distribution for a particular carbon arc system. The values of the maximum intensity are in good agreement but the distribution is narrower than that calculated, presumably as a result of obstruction.
