In this case, the SC6000 camera (Flir systems) is used; for the purpose, the system is equipped with a Lock-in module that drives the halogen lamp to generate a harmonic thermal wave of selectable frequency / and the IRLock-In[C] software.
In previous equations, NS is an arbitrary number of thermal wave reflections to be considered (the smaller diffusivity, the higher NS value).
Award: Upgrade existing thermal wave imaging thermography system
Effects of stiffness and thermal relaxation times on the amplitude ratios for incidence of various plane waves, for example, longitudinal wave (P-wave), thermal wave (T-wave), and transverse wave (SV-wave), are depicted numerically and shown graphically with angle of incidence.
Among them are discussions of characteristics of laser-generated visco-elastic Rayleigh waves, selective optical gas sensors using butterfly wing scales nanostructures, fabricating a monolithic integrated bimaterial resonant uncooled infrared sensor, different kinds of carbon-based material for resistive gas sensing, direct surface relief formation in polymer films, using a microwave sensor as an online indicator of neurological impairment during surgical procedures, improving amorphous selenium photodetector performance using an organic semiconductor, and evaluating the polarization state of integrated piezoelectric sensors and actuators using the thermal wave method.
Since the efficiency of the basic adsorption refrigeration cycle is low, and the cooling output is not continuous, many advanced adsorption refrigeration cycles (such as the heat recovery cycle, mass recovery cycle, thermal wave cycle, forced convective thermal wave cycle, etc.
The frequency-dependent thermal wave Equations (6) and (7) can be used to analyze the resultant thermal field.
Like a collection of flotsam propelled along the surface by waves traveling across the ocean, it turns out that a thermal wave -- a moving pulse of heat -- traveling along a microscopic wire can drive electrons along, creating an electrical current.

theta]] is the thermal wave speed; Q(t)-the thermal field in time interval [0, [t.
Temperature oscillation amplitudes between layers were compared to the outer surface temperature oscillation amplitudes in order to get thermal wave attenuation measured during the experiment.
