Wave-front coding technology is a novel jointly optical and digital imaging technology which can greatly extend the depth of focus of optical systems. The image restoration process is an important part of wave-front coding technology. Using wave-front coding makes the modulation transfer function(MTF) values of the optical systems change little over a range of several times the depth of focus
which means the system MTF is quite insensitive to defocus
and there is no zero in the passband. So we can design a single filter for the restoration of images in different defocus positions. However
it's hard to avoid noise during image acquisition and transmission processes. These noises will be amplified in the image restoration
especially in the high frequency part when the MTF drop is relatively low. The restoration process significantly reduces the system signal to noise ratio this way. Aimed at the problem of noise amplification
a new algorithm was proposed which incorporated wavelet denoising into the iterative steps of Lucy-Richardson algorithm. Better restoration results were obtained through the new algorithm
effectively solving the noise amplification problem of original LR algorithm. Two sets of identical triplet imaging systems were designed
in one of which the cubic-phase-plate was added. Imaging experiments of the manufactured systems were carried
and the images of a traditional system and a wave-front coded system before and after decoding were compared. The results show that the designed wave-front coded system can extend the depth of focus by 40 times compared with the traditional system while maintaining the light flux and the image plane resolution. 2010 Copyright SPIE - The International Society for Optical Engineering.

In order to realize the fast test for the interpolation error
the graph fitting test method for the interpolation error of Moire fringe is put forward in this paper. Firstly
the triangular wave Moire fringe photoelectric signal of the encoder whose phase difference is 90 are sampled to get the Lissajous graph of the two signals. Secondly
the single wave represented by the founded subsection function is used to fit the practical Moire fringe Lissajous graph. Then
the fitting result is tested to verify whether it satisfies the accuracy requirement. Lastly
the founded subsection function instead of the practical wave function is used to calculate the interpolation error. Using the graph fitting method to sample the Moire fringe single of 15-bits photoelectric encoder to get the interpolation error curve
the tested maximum interpolation error is 70" and the minimum error is - 69". Comparing with the interpolation error which is received from traditional test method
the change trend of the interpolation error curve is similar
and peak-peak value is almost equality. The results of experiment indicate that: the equipment is convenient and the examination method is efficient and feasible. The measure speed is fast and the manifestation result is intuitionistic. The system can be used in the working field. The method can avoid the speed influence and realize the dynamic interpolation error measure
which is significant for the research of encoder's dynamic accuracy characteristics. 2009 IEEE.

The dynamics in the Bose-Einstein Condensation(BEC) process with interaction between two energy-level Bose atoms and single-mode active cavity field in the quantum cavity is analyzed using the ordinary method suggested by the authors for solving the wave function in the Schrodinger ideal from the Heisenberg idea. A wave function has been established for the atoms under the BEC conditions in the quantum cavity. Then the stability factor determining the BEC and the selection rules of the quantum transition can be solved.
