RESUMEN
In this work, a modulated photothermal radiometry principle is applied in a scanning configuration. This technique was developed with the aim of performing imaging and thermal characterization at the microscale and exploring characteristic times lower than those accessible by infrared thermography. The use of a heat source smaller than the measurement area provides high sensitivity to in-plane heat diffusion. Application to quantitative thermal characterization of advanced micro-structured materials is demonstrated.
