An on-line thermocouple auto-calibration system using wireless communication module for ceramic kilns has been developed. It is consist of the temperature measurement module for the ceramic kilns, Wireless transmitting and receiving module, data processing and results display module of the PC. For the requirement of thermocouple calibration for ceramic kilns, the wireless data transmission module is used to transmit temperature data in the system. Finally, the data is transmitted to PC through serial interface, it is processed and the calibration results are derived by PC. Its performance fully met calibration requirements. The calibration efficiency of the system is greatly enhanced and the additional man-made errors are reduced. The proposed system ran well in practice.

Measurement of fluorescence lifetime plays an important role in fluorescence lifetime imaging technology. If the Time correlated single photon counting method is used to process the signal of fluorescence lifetime images, it can make the real time imaging which have the virtue of high timing resolve and high signal to noise ratio. Multi-wavelength channels are used to record the lifetime simultaneously in four-dimension TCSPC system design. Four-dimension TCSPC imaging can be used to record the photon density over time, wavelength and coordinates of the scanning area. Analysis shows that the counting efficiency and the amount of information in the data can be increased by recording the fluorescence in several wavelength channels simultaneously. Multi-wavelength imaging was also successfully used to separate different fluorephores in stead-state images.
