1. The function of the system is then explained exemplary by a polarimetric heterodyne reflectometer and an imaging radiometer.

2. Emissivity corrected radiation pyrometer integral with a reflectometer and roughness sensor for remote measuring of true surface temperatures

3. The winding technology of fiber coil used in fiber optic gyroscope was demonstrated. The principle and application of Brillouin Optical Time Domain Reflectometer (BOTDR) were introduced.
