Abstract :
An advanced temperature control system has been developed for calorimetric method of electromagnetic wave power measurement. The temperature deviation can be reduced by repeatedly substituting the controlled variable through a DA converter and an adder. The system has been applied to a calorimeter for laser power with experimental results yielding good agreement with analytical predictions.
