This paper presents the disturbance compensation scheme based on liquid crystal steering system according to the problem that satellite platform vibration affects the tracking and pointing accuracy in space optical communication. The mathematical model of liquid crystal steering system is built. For improving convergence speed
the adaptive controller based on posteriori estimation errors RLS lattice filter is designed
which not only achieves fast adaptation
but also reaches optimal steady-state disturbance compensation. Finally
the simulation results show that this control scheme is valid and feasible. (2012) Trans Tech Publications

The piezo-electric steering control system is used to compensate the vibration of satellite platform. The mathematical model of piezo-electric steering system is built. The adaptive controller based on improved LMS filter algorithm is designed according to this system characteristic. The adaptive delay filter is designed to solve slow convergence speed problem of traditional algorithm. Meanwhile
the adaptive delay filter can also compensate phase delay of control circuit. The adaptive deviation filter is introduced and it effectively compensates the vibration deviation which is low frequency and high amplitude. The experimental results show that the remained errors are rad
which meets space optical communication requirement and proves that this control scheme is valid and feasible. (2012) Trans Tech Publications

When developing BIOS or device driver on PC Platform
it's necessary to access PCI configuration space and PCI Express extended configuration space. The register organization in PCI Express configuration space was detailed
PCI capability structure and PCI Express Extended Capability structures were emphasized here. A way of accessing device configuration space utilizing flat memory addressing was given
and its raw code was obtained on a Intel G31 chipset based PC. 2010 IEEE.

A set special detecting system is proposed based on TDICCD push-broom technology applying in dynamic imaging detecting experiment of space optics remote sensor. In the system
In the course of detecting
push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555/s
regard Nyquist frequency target as detecting aim
within the range of 5 and control precision on steady speed achieves 0.3%
in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom
make matching simplify
enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical
the level and 45 the direction 0 fields of view
0.86 the field of view Nyquist frequency target strip image after detected
a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed. 2010 Copyright SPIE - The International Society for Optical Engineering.

A fast algorithm is proposed to restore the color images
degraded in a deterministic way by motion- blurred
by multichannel combination processing. Based on the color space conversion model
the point spread functions of the image motion on each plane of YUV422 image can be achieved. The U
V plane of YUV422 images are combined to form a new UV plane which has the same size as Y plane. Then
the Y
UV plane are packed into a two dimensional complex array which can be transformed directly by FFT and result a composite frequency spectrum. Wiener filter is applied to filter Y
UV spectrums separated from the composite spectra. On Graphics Processing Unit (GPU) platform
the proposed algorithm can restore a 1024x1024 24-bit motion-blurred color image in 7.95ms
and the PSNR of the restored image is 27.12 which reveals a good restoration performance. 2009 IEEE.
