A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied
which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion
and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio
high precision
compact structure
high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera
the location relationship between the displacement of focusing structure and the focal plane movement is derived
and the system error is analyzed
its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70
repeated positional accuracy is 2m
which meet the requirements for use. 2010 SPIE.

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 antiinterference and high scalability
this system has stable and reliable performance. 2010 IEEE.

Microstructure fiber is a new kind of optical fiber. An arrangement of air holes running along the full length of the fiber provides the confinement and guidance of light. The light is confined in the silica core along the fiber axis. This fiber has endlessly single mode
special dispersion characteristics and so on. Using a vectorial effective-index numerical method
we investigated the dispersion characteristics of a microstructure fiber with honeycomb cladding structures. The dispersion
dispersion slope
and Kappa parameter can be designed neatly by changing the air hole size and the separation of the holes in fiber cladding. We demonstrated the Microstructure fiber with large absolute value of normal dispersion and negative dispersion slope at the wavelength of 1550nm. Conventional communication non-shifted single-mode fibers and nonzero-dispersion shifted fibers (NZ-DSF) can be compensated efficiently using the microstructure fiber at the wavelength around 1550nm.
