In this paper
we proposed a novel coding scheme is proposed using wavelet-based CS framework for nature image. First
two-dimension discrete wavelet transform (DWT) is applied to a nature image for sparse representation. After multi-scale DWT
the low-frequency sub-band and high-frequency sub-bands are re-sampled separately. According to the statistical dependences among DWT coefficients
we allocate different measurements to low- and high-frequency component. Then
the measurements samples can be quantized. The quantize samples are entropy coded and forward correct coding (FEC). Finally
the compressed streams are transmitted. At the decoder
one can simply reconstruct the image via l1 minimization. Experimental results show that the proposed wavelet-based CS scheme achieves better compression performance against the relevant existing solutions.

In order to measure high accuracy or mid spatial frequency optical surfaces
this study investigated imaging system in Fizeau interferometer. Interferometer is a transferring phase information system. General transfer function can't evaluate the ability of imaging system in interferometer that transfers the phase information of the optical surface. So this paper deduced instrument transfer function (ITF) and used ITF to evaluate the phase information transfer ability of interferometer. We obtained some results about ITF of imaging system by numerical simulation when there are different aberrations in imaging system or measuring optical surfaces were different. Our results indicate that ITF can evaluate the ability of transferring phase information in interferometer and the distortion of imaging system evidently affects the accuracy of interferometric measurements. 2010 IEEE.

The anti-symmetric modes (A01 mode for low frequency
A 03 mode for high frequency) and symmetric modes (S0 mode) produced by Lamb wave sensor are used to detect multi-parameters of a liquid
such as its density
sound velocity and viscosity. These modes are found to be very different to the parameters. For example
the A01 mode is very sensitive to the liquid's density but the A03 mode is sensitive to its sound velocity. The measurements of the attenuation with S0 mode can give out liquid's viscosity after its density been determined by A 01 mode. That could be a way to distinguish an unknown liquid with high sensitivity or to solve the problem of the selectivity of label free detection on biosensors. 2011 IEEE.
