Paper Abstract

A method is reported for estimating thermophysical and optical parameters, in which a two- spectral band sandwich photodetector is used. The sensitivity ranges of such a sensor are 2 - 5 micrometers and 8 - 14 micrometers . On irradiating an object's surface by a short radiation pulse the photodetector collected signals U1, U2 and the rates of their changes (dU1/dt), (dU2/dt) are recorded. These pertain to the same area on the object's surface and belong to the two spectral ranges mentioned. The parameters of the object are evaluated by means of calculations with the values measured.
