Abstract
The present disclosure is directed toward a method that includes acquiring, by an imaging device, a thermal image of a heating surface of a heater assembly. The heater assembly includes a heating surface for heating a heating target, and the heating surface defines a plurality of heating zones. The further includes determining variations in the plurality of heating zones based on the thermal image of the heating surface. The the thermal image includes a plurality of pixels corresponding to the plurality of heating zones in the heater assembly.
Claims20
A method comprising:
- acquiring, by an imaging device, a thermal image of a heating surface of a heater assembly, wherein the heater assembly includes a heating surface for heating a heating target, and the heating surface defines a plurality of heating zones;
- and
- determining variations in the plurality of heating zones based on the thermal image of the heating surface, wherein the thermal image includes a plurality of pixels corresponding to the plurality of heating zones in the heater assembly.
A method comprising:
- emitting, by a controller, a stimulus at a heating surface of a heater assembly, the stimulus causing a disturbance to a predetermined temperature of the heating surface, wherein the heater assembly has the heating surface and a plurality of heating elements for heating a heating target;
- receiving, by a control system from the controller, stimulus information;
- and
- controlling, by the control system, the heater assembly to maintain a predetermined temperature profile on the heating surface based on the stimulus information from the controller.
