Method and apparatus for controlling heating of an object in a heating chamber (System for Controlled Heating An Object)

摘要

The radiation generated by at least one radiation source is adjusted to produce a constant radiation intensity whereby the object can be heated and the radiation intensity from an object of the first wavelength is reduced to at least one of the current Is detected until it is equal to the radiation intensity, whereby the temperature of the object has a predetermined value. From this time on, the evolution of the object to the actual temperature is precisely adjusted in accordance with the determined program, the radiation intensity from the object at a second wavelength longer than the first wavelength is sensed and a measurement signal representative of the sensed radiation intensity is used, So as to continuously adjust the intensity generated by the sensor.
