Induction cooktop with infrared and far-infrared temperature detection

An induction cooktop, comprising:

• a glass-ceramic substrate defining a cooking surface and an underside opposite the cooking surface;
• an induction heating coil positioned beneath the underside of the cooking surface;
• an infrared sensor, configured for detection of electromagnetic radiation in a wavelength range of between 750 nm and 3000 nm, directed toward the underside of the glass-ceramic substrate and outputting a first temperature reading of the glass-ceramic substrate during heating of a cooking article positioned on the cooking surface using the induction heating coil;
• a far-infrared sensor, configured for detection of electromagnetic radiation in a wavelength range of between 3000 nm and 10,000 nm, directed through the glass-ceramic substrate and outputting a second temperature reading of the cooking article and the glass-ceramic substrate;
• and
• a controller determining a temperature of the cooking article using the first temperature reading from the infrared sensor and the second temperature reading from the far-infrared sensor.
