abstract = {The photothermal deflection technique, also known as "mirage
effect", is a nondestructive method of evaluating thermal
properties of solid, liquid or gaseous species. This technique
will be used to detect pollutant absorption. As the deflection is
stronger in liquids than gases, we will first consider the
deflection in paraffin oil. We consider a medium that is heated
by a modulated laser diode beam, and we measure the deflection of
the probe beam passing through the heated region as a function of
the distance between the axes of the beams. After some
theoretical considerations and numerical simulations, we present
the application of this method to the experimental determination
of the thermal diffusivity of a liquid sample in excellent
agreement with previously known values.}
