Differential Equations Applied to Photopyroelectric Detection
Equações Diferenciais em Detecção Fotopiroelétrica
Keywords:ppe, detection, vegetable oil.
The present research aimed to study the technique of photopyroelectric detection, it is specifically setting SPPE. Besides performing graphics simulations analytical amplitude and phase of the thermal signal due to the modulation frequency generated to obtain ownership for a sample thermal diffusivity of vegetable oil.
