Time Domain

A time domain analysis is based on changes in physical signals related to time. A time-domain graph shows how a signal changes over time. In the case of ThermoreflectanceThermoreflectance is a method for determining the thermal diffusivity and thermal conductivity of thin films with thicknesses in the nanometer range.thermoreflectance or the laser flash method, the detector signal (voltage change) is recorded – at a minimum – over the time range between the energy input and the signal maximum (e.g., RF mode) or as a function of the expected heat diffusion time (e.g., FF mode).
