Abstract
A method, apparatus and computer program can include applying a pulse edge to a resonant circuit including an inductive element (for inductively heating a susceptor) and a capacitor, wherein the applied pulse edge induces a pulse response between the capacitor and the inductive element of the resonant circuit, wherein the pulse response has a resonant frequency; determining a period or frequency of the resonant frequency of the pulse response; and converting the determined period or frequency into a temperature estimate based on a temperature gradient and a calibration measurement.
