Abstract
Generally and not exclusively, a microwave cooking oven to cook food in a microwave chamber includes at least one array of radiation detectors. An exemplary method includes sensing an optical depth of the item along each of multiple beam paths from at least two sides of the item, and mapping isothermal regions in the interior of the item 3-dimensionally based on the sensing. Another exemplary method includes sensing a microwave power representing a value of a heatability property for each of multiple regions of the same item, and applying a different measure of the microwave power to each of the different regions according to the value of the heatability property in each individual region. Yet another exemplary method includes sensing different frequencies of the microwave power in the microwave chamber, and changing the frequency of the microwave power for heating the item, as the item undergoes heating.
