Abstract
An instrument for determining thermal diffusivity of disc shaped opaque solid or quasi solid materials using a high intensity short duration flash of light from a single LED, a planar LED array, or laser diode source is disclosed. This instrument comprises an axially and radially indexed cylindrical sample holder able to accommodate a plurality of test samples and sequentially bring them into a designated testing position to expose one face of each sample to the flash of light while the obverse face of the disc is observed by a temperature measuring device, for the purpose of recording the attendant thermal excursion. An improved calculating method, based on empirical data observed during each test, is used for calculating thermal diffusivity.
