COMPUTATION OF THE EMISSIVITY OF A CYLINDRICALLY SYMMETRIC LIGHT SOURCE FROM MEASUREMENTS OF THE PROJECTED INTENSITY PROFILE

Abstract

A method is described for computing the emissivity of a cylindrically symmetric, optically thin light source, when the projected intensity profile is known from experiment. The unknown function is taken as a series expansion in terms of orthogonal polynomials, and it is shown how the expansion coefficients can be determined. This procedure yields a least-squares smoothed approximation.
