Double exponential algorithm of photon correlation spectroscopy (PCS) is realized by the nonlinear estimation, its inversion accuracy is affected by four initial parameters choice. According to linear relationship of the decay linewidth distribution coefficients and exponential terms of autocorrelation function (ACF), a new inversion algorithm combining linear and nonlinear estimation is proposed. By changing four parameters optimization problem into two parameters optimization problem in turns, new algorithm improves the inversion accuracy and reduces two initial parameters. By new and tradition algorithm, ACF of 200nm – 600nm bi-dispersed particles is respectively inversed. For noise-free ACF, inversion error of new algorithm is 0, which is at least better than tradition algorithm 2.01%. For inversion of noise ACF, compared with tradition algorithm, new algorithm can reduce inversion error by 0.93% ∼ 6.43%. Therefore, new algorithm is superior to tradition algorithm in inversion accuracy and tolerance of noises.

SAR images despeckling is one of the most important research subjects in SAR images processing. Following discussion on the advantage and disadvantage of curvelet and wavelet transforms based SAR images despeckling, an algorithm which combined curvelet and wavelet transforms was proposed for despeckling of high resolution SAR images. Firstly, the curvelet and wavelet were used to denoise the original SAR image, then the related residual image between their results was acquired, which was then denoised through the curvelet transform. Finally the denoised residual image was added to the curvelet denoised image. Experimental results of TerraSAR-X high resolution images indicated that, compared with the Enhanced Lee filter, the Enhanced Frost filter, the wavelet transform based and curvelet transform based methods, the algorithm presented here had well despeckling effect, as well as fine edge-preserving ability.

Due to limited sensing range for sensors, moving object tracking has to be realized by relaying from one sensor to the other in sensor networks, and so the tracking procedure can be modelled as a Markov chain system. Based on the Bayesian theory, we propose the relaying Kalman filter(RKF) algorithm which introduce the equations of updating sensor probability, and reconstruct the innovation equation. Furthermore, the extension of the proposed method can be applied in nonlinear dynamic system. Finally, simulation results show the effectiveness of the proposed RKF algorithm.

A wavelength scanning demodulation system based on continuous wave tunable frequency is given in this paper. Based on fiber Bragg grating's (FBG) axial strain character, the practical FBG strain sensor is designed. At the same time, tunable narrow-band light source, which is composed of wide-band light source and tunable optical filter, is adopted to demodulate multiplex signals. This method not only supply wider tunable range but also afford higher signal to noise ratio. A mixture multiplexing method that combines optical frequency domain reflectometry (OFDR) and wavelength division multiplexing (WDM) is proposed to address FBG sensing network. The proposed system scheme is testified to have faster demodulation and higher stability by analyzing theoretically and researching experimentally.
