Air-bearing is a core component of air-bearing rotary stage. The weakness that the air-bearing has the low load capacity and stiffness has been concerned about by domestic and foreign scholars. So how to improve the load capacity and stiffness has become a serious problem. In order to improve the load capacity and stiffness of the air-bearing rotary stage  in this paper  we improved structure of Zhang Wenjie and others' high-precision direct-drive air-bearing rotary stage. The gas film of air-bearing has been meshed by GAMBIT software  and we use FLUENT software to obtain the carrying capacity features of the gas film. Finally  the structural static force of the precision air-bearing rotary stage will be analyzed by ANSYS software. The analysis results show that: the structural design of the precision air-bearing rotary stage is reasonable  and this structure can provide a larger range of loads. Even in heavy load conditions  a larger deformation will not occur any more. It has a good practical value  and also can be widely used in high precision equipments. (2012) Trans Tech Publications.

To obtain high resolution  high signal-to-noise ratio (SNR)  high reliability and real time in wide spectral range  we study the space modulation Micro Fourier Transform Spectrometer (FTS) based on multi-step mirrors covering the spectral range of 3-5m and 8-12 m in theory and experiment. The influences of spectrum reconstruction caused by the diffraction and extended light source in Fourier Transform Infrared Spectrometer (FTIR) are analyzed. A method to reduce the noises in spectrum reconstruction and the relationship between coherent intensity and solid angle of light source are discussed. An extended light source with suitable size is chosen  considering the requirement of SNR and spectrum resolving power in the optical design. Furthermore  the fabrication of micro multi-step mirrors  which is the core part of FTS  is investigated. Three methods for fabricating multi-step micro mirrors are demonstrated. 2011 IEEE.

Control and management of the urban traffic signal is an problem that modern city has to face. The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC  which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1  and is used as the core part of the system. As a new try  the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.

A test method for dynamic imaging of space TDICCD (Time Delay and Integration Charge Coupled Devices) camera was presented in this paper. The test method adopted the PLL (Phase Locked Loop) technology and CMAC (Cerebella Model Articulation Controller) friction compensation as control strategy. Furthermore  According to this method  a test system for dynamic imaging of space TDICCD camera was designed and implemented. The system simulated the movement of the ground objects relative to the space aerocraft  to validate the capability of image speed match and the dynamic imaging quality of TDICCD camera. The design adopted a precision turntable and a drift turntable to simulate the movement around the earth and the drift motion in different latitude due to the rotation of earth  of the aerocraft. The turntables were drived by permanent magnet torque motor which was powered by PWM (Pulse Width Modulation). The system adopted DSP (Digital Signal Processor) as the control core and reached a very high performance. The experimental results showed that the steady speed error was better than 0.01 % and the instantaneous speed error reached 0.0267%. The precision of the test system designed met the requirement for dynamic imaging of TDICCD camera. 2010 IEEE.

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.
