Abstract
A method and apparatus for sensing properties of glass-ceramic cooktop appliance having at least one burner assembly disposed under a glass-ceramic plate. The sensor assembly includes a waveguide having a first end disposed in the burner assembly and a second end disposed outside of the burner assembly, and at least one detector located adjacent to the waveguide's second end. A radiation collector is located adjacent to the first end of the waveguide so as to direct incident radiation substantially paraxially into the waveguide. The method includes collecting radiation from the glass-ceramic plate, and directing the collected radiation onto a detector located outside of the burner assembly via a waveguide.
