Posture Measurement

At present MEMS inertial devices is unable to satisfy the precision request of the inertial posture measurement system. This paper has designed a gyro dynamic data generator for simulation according to the gyro signal characteristics.The signal produced by the generator is specified as the gyro data and the optimal estimator for data fusion is designed by using the Kaman filter algorithm.The multi-segment data is analyzed and identified while the optimal data is estimated .The results show no matter how the correlation of the data is, the fusion data has attenuation of 10dB in noise, with its signal-to-noise ratio being enhanced more than 2 times at least.

Photonic Bandgap Fiber

The sensing setup for detection and measurement of carbon dioxide and methane was designed. Absorption spectra of many compounds indicate several weak peaks around 1400-1600 nm wavelength. Thus, tunable lasers with 20 micron core photonic bandgap fiber matching above wavelengths were chosen for the optical measurement system. Measurements were performed at low pressure to eliminate pressure broadening effect and to sharpen the absorption peaks. The angled cut was performed to improve signal to noise ratio.
