The method for self diagnose and self repair of composite materials using hollow optical fiber with injected adhesive is first put forward. The investigation and analysis of pass light mechanism of hollow optical fiber are made in detail. The measurement principle, method and experimental research on self diagnose of the rupture place in composite materials by using hollow optical fiber are also put forward. Experiments on composite materials with or without embedded optical fiber are performed according to Chinese test standards in order to find out the comparable characters. Based on the experimental results, it is found that there is only little difference on the mechanical behavior of composite materials with or without embedded hollow optical fibers. In other words, this method can be used in engineering practice, such as in smart structures and other fields. Finally the general scheme of the entire system is given.

Based on dual-differential comparing principle, an experimental system of optical fiber F-P interferometric micro-displacement measurement is introduced. It is capable of achieving the absolute displacement measurement, and wavelet transforms is adopted as theory fundament to extract the optical F-P interferometric characteristic signal and remove the noise, so its resolution can reach 0. 01 μm in the dynamic range of 0～ 1 mm.

In order to increase the transmission distance and reduce noise effectively, a communication system with the optical fiber interface is developed in this paper. In the system, the PCI bus is adopted as the connection bus between the underlying optical fiber transceiver module circuitry and host computer using the WDM driver. The FPGA is the core logic of the whole system, responsible for data transmission and timing logic control. The module structure and the design method of the PCI bus, the principle and the design of optical interface module and the bottom-driven development are described in this paper. The experiment results show that the system has basically meet requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. With long transmission distance, strong anti- interference and high scalability, this system has stable and reliable performance.

The transmission of optical wave in fiber is analyzed,and the asymmetry of transmission delay which results from phenomena of chromatic dispersion is computed under the condition of DWDM（density WDM）and SWDM（sparse WDM）.Then we proposed a scheme of DWDM transmission delay compensation in time transmission using optical *** theoretical calculation shows that when calculated on 50km transmission range,the time difference when using two waves of wavelength difference of 1nm is nearly three orders of magnitude less than when using two waves of wavelength of 1550nm and 1310nm.

TiO2 Coating on Optical Fiber with Different Slurry States

The 3～〔rd〕International Conference on High-Performance Ceramics(CICC-3)（1）

作者： Yirong Liu Jiachen Liu Boran Tian Yanqiu Wei and Yuhong Zhao Key Lab of Advanced Ceramics and Machining Technology Ministry of Education Tianjin China

＜正＞ In order to meet a need of application of photocatalyst, a slurry dipping method was adopted for nano-TiO2 coating on optical fiber. Three slurry states were designed and their effects on coating quality were investigated. Experimental results showed that paste state may lead to surface cracks in coating. Both flocculent and dispersive slurry states can form high quality coatings whose coating microstructures are different, the former resulted in a loose and thicker coating and the later resulted in a dense and thinner coating, which supplied a basis for further study on effect of photocatalytic reaction and design of photocatalyst reactor.
