E-O stabilization platform performance is partly decided by gyroscope precision
so it is important to choose a gyroscope with proper accuracy for an E-O stabilization platform. Based on the method of using a gyroscope in practice
gyroscope error model is established. With the gyroscope error model gyroscope accuracy parameters
that is bias repeatability
bias stability
scale factor
scale factor nonlinearity
output noise and bandwidth
are separately analyzed. According to the concretely required performance indices for an E-O platform
means of distribution of gyroscope accuracy parameters is proposed. A MEMS gyroscope is tested to get the parameters. Bias stability of the gyroscope is 0.08 /s while the bandwidth is 60 Hz. Output noise both at zero input and at nonzero input is analyzed by means of PSD to get the result that nonzero output noise is higher than zero output noise. Frequency response result of the gyroscope is dealt by means of correlation analysis. With all the tested result and the method of distribution of gyroscope accuracy parameters
it is clear that how the gyroscope errors works in an E-O servo system. The principle of distribution of gyroscope accuracy parameters is helpful for choosing appropriate gyroscope for an E-O platform. 2011 IEEE.

The threshold voltage of a-Si: H/SiNx TFT will shift under long time gate bias stress
it is mostly leaded by charge trapping in gate insulator and defect creation in semiconductor. And it is hard to be applied in AMOLED for TFT because of its threshold voltage shift. In allusion to the phenomenon of charge trapping
a series of SiNx insulating films in different N/Si(0. 87 -1.68) ratio were deposited by PECVD in this paper
controlling different flow ratio of source gas SiH4 and NH3
and a great deal of tests (ellipsometer
infrared absorption (FTIR) and Electron Dispersion Spectrum (EDS) test ) were done on these samples. Based on these SiNx insulators
three different capacitance samples in MIS structure were done
degraded experiments and C-V tests on these samples were done. The C-V curve shift of capacitance which contained SiNx with slightly N-rich(N/Si is bigger slightly than 1. 33) was not evident before and after degradation
this result indicated that the defect density of this type SiN x was smaller
and could restrain charge chapping in the interface of a-Si:H/SiNx effectively. So that as gate insulator of TFT
SiN x with slightly N-rich could decrease the threshold voltage shift of TFT and enhance its stability effectively.
