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

In view of the current stringent need to the real-time compression algorithm of the high-speed and high-resolution image
such as remote sensing or medical image and so on
in this paper
No List SPIHT (NLS) algorithm has been improved
and a fast parallel SPIHT algorithm is proposed
which is suitable to implement with FPGA. It can deal with all bit-planes simultaneously
and process in the speed of 4pixels/period
so the encoding time is only relative to the image resolution. The experimental results show that
the processing capacity can achieve 200MPixels/s
when the input clock is 50MHz
the system of this paper need 2.29ms to complete lossless compression of a 512x512x8bit image
and only requires 1.31ms in the optimal state. The improved algorithm keeps the high SNR unchanged
increases the speed greatly and reduces the size of the needed storage space. It can implement lossless or lossy compression
and the compression ratio can be controlled. It could be widely used in the field of the high-speed and high-resolution image compression. 2010 IEEE.

We investigated electro-optic modulator structures to target low drive voltage
high-speed modulation
and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study
the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films
the frequency-voltage-size performances for 2.5GHz
10GHz
40GHz
and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V
1.6V
3.0V and 4.8V
respectively
for the ideal film with r51=730 pm/V at 1550nm wavelength
where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm
0.8 mm
0.4 mm and 0.2 mm
respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation
an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured
which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.
