Measuring apparatus for the determination of a temperature of an object, the use thereof and method for the operation thereof, as well as thermotherapy device with such a measuring apparatus

A thermotherapy device comprising:

• a support for a person;
• a measuring apparatus comprising:
• an infrared camera with an infrared camera focus;
• a calibrating device connected to the infrared camera via a data link, wherein the calibrating device has an outer shell with an emissivity on the outside similar to that of the person;
• and
• a temperature sensor arranged in the outer shell, the calibrating device being configured to determine a correction factor based on a relationship between a temperature of the outer shell and a radiation output of a determined emitted wavelength range of the outer shell and the calibrating device being configured to associate a temperature with a determined radiation output of an emitted wavelength range of a measuring surface of the person, taking the determined correction factor into consideration.

A method for the determination of a temperature of an object, the method comprising the steps of:
