Abstract
A measurement configuration is discussed where shutters are placed in front of the imager and the flash lamps. Proper timing for the opening and closing of the shutters eliminates a direct interaction between the imager and flash lamps for a single sided measurement, enabling accurate measurement of the thermal response of a specimen. The time dependence of the thermal response is analyzed to produce an image of the effective diffusivity of the specimen.
