Abstract
The optimum use of a thermal imaging source requires a knowledge of the irradiance distribution within the region of maximum beam convergence. In the case of a pulsed source, this requirement is even more severe, since there is no opportunity to reposition the sample during exposure in order to find the ideal geometry. Thermal damage studies nearly always employ sources which have rapid shutter systems producing pulses of variable length, and one of the major problems is that of characterizing and measuring the “image volume” within which experiments are to be carried out. It is desirable to know in advance the irradiance distribution which will impinge upon the sample surface, and also to know how this will be altered if damage is sustained and a part of the sample is vaporized.
