In industrial technological processes associated with the heating of the processed material by microwave radiation, it is necessary to measure the temperatures of objects. Methods for measuring temperatures in the fields of technology using microwave heating systems are considered. The main possibilities, disadvantages and limitations of the used contact and non-contact (optical) measurement methods are determined. The requirements for temperature measurement systems under conditions of exposure to strong electromagnetic fields are listed. The possibilities of the spectral pyrometry method are especially noted.

Radius Compensation

Blades are an important part of aviation engine, its manufacturing compliance seriously affect the performance of the engine. Blades tend to be free-form surface modeling, which makes it extremely difficult to measurement. Since no probe radius compensation, high efficiency, non-contact optical measurement methods get more and more attention, but the inspection uncertainty of optical measurement is usually between 30um to 50um .To reduces the optical non-contact measurement uncertainty, this paper presents an Optical-triangulation-based method for measurement of blade sections. There is a data optimization process in the method, and this feature makes the proposed method can obtain better measurement results. At last, some experiments demonstrate the effectiveness of this method.
