Published: July 2013

Optical freeform surfaces are complex surfaces with non-rotational symmetry that break through the limitations of conventional optical element, and are widely used in advanced optics application for system configuration simplifying and performance enhancing. Interferometric test with computer generated holograms (CGH) has been widely used in the aspherical surfaces testing for their unique wavefront transformation, as well as the freeform surfaces testing with high precision. As an important parameter, it is different at the definition of asphericity in freeform surfaces manufacture and test. Asphericity for interferometric test which verifies the testing ability of the CGH and determines testing system initial configuration was calculated with minimum maximum angle deviation. Reverse ray tracing could get the optimal solution of CGH local phase at certain location in the CGH design. For the non-rotational symmetry of freeform surfaces, the phase of sample point in CGH surface should be calculated in three-dimensional coordinate system. The calculation method of discrete phase was deduced by ray tracing, as well as the phase distribution on freeform surface were proven by calculating in such way. The results were compared with simulation by optical design software. It shows that the method is right and high accuracy to be used in the CGH design for the freeform surfaces.

Gaussian-Geometric Moments and its Application in Feature Matching
Authors: Zhang Chao Xin , Xi Ping , Dai Mo
Published: July 2013

Since the 7 famous Hus invariants had been introduced in 1960s, the moment invariants play an important role in image analysis and pattern recognition. In this paper, we propose a new moment called Gaussian-Geometric moment, and derived their translation and rotation invariants. One significant conclusion drawn is that the rotation invariants of Gaussian-Geometric moments have the identical forms to those of geometric moments.The Gaussian-Geometric moments and the geometric moments both can represent the image information, difference is that the Gaussian-Geometric moment can represent the center information of an image and the geometric moments represent the edge information of an imageonly. This is particularly evident in the performance of high order ones. Another important property of Gaussian-Geometric moments is that it has a scale parameter which allows choosing the best scale to represent the interest region of an image. A detailed comparison has been made to test the feature matching capability between the proposed moments and the geometric moments. The results show that the proposed moments perform much better than the geometric ones.

Authors: Peng Qing Xi , Chen Jun Wei
Published: July 2013

Online review can help people getting more information about store or product. The potential customers tend to making decision according to it. However, driven by profit and fame, spammers post spurious reviews to mislead the customers by promoting or demoting target store. Previous studies mainly focused on the text features of the reviews. However, these studies ignore the importance of relationship between store and reviewer. This paper first proposes a novel concept of store robustness which means the degree that store resist the influence of spamming. Then which types of store the spammer prefer to choose to gain larger influence is discussed. The proposed method use store-reviewer relationship combined with deviation degree to calculate the spamicity (degree of spam) of reviews. A subset of highly suspicious reviewers is selected for evaluation by human judges. Experimental results show that the proposed method can find out the harmful store review spammer efficiently.

This article introduced a fast and stable method on measuring the batches of trace moisture in ultra-purity ammonia gas .This method is based on ammonia decomposited reaction ,which occurs completely and irreversibly when ammonia is passed over nickel catalyst at high temperatures. While the trace water wapor passes though the catalyst unchanged. And the moisture of ammonia may be determined by measuring the dew point of the steam of hydrogen and nitrogen produced by decomposition of ammonia,combined with the trace oxygen content measured by GC,the content of trace moisture in ultra-purity ammonia gas can be got. Contrasted with Cavity Ring-down Spectroscopy (CRDS) and Infrared Absorption Spectroscopy (IR),Thermal Decomposition Dew Point method (TDDP) has high accuracy,good repeatability, stability and environmentally friendly.

A fiber Bragg grating (FBG) sensing network for vibration measurement is proposed and demonstrated in this paper. The light source of the described sensing technique is an erbium-doped fiber laser applying a 980-nm laser diode and a fiber Fabry-Perot tunable filter. The fiber laser has a 40nm tuning range, allowing many vibration sensors to be multiplexed on the same fiber. Reflected light wavelength shift of the FBG sensor caused by strain variation is converted to intensity deviation, which avoids a complex demodulation process. This sensing scheme can effectively increase the demodulation speed of sensing system up to 20 KHz. At least 20 FBGs can be multiplexed alone a fiber.

Published: July 2013

In this paper, the authors discuss the influence of touch trigger probe system on CMM measurement performance based on measurement experiment results. A ring gage and a plug gage finished in high accuracy are employed as test pieces and the measurements performed under the conditions of combining different extension bar and approaching speed. Two main types of errors, periodic component and high frequency undulation, are verified. Introduction of the extension bar may significantly aggravate the accuracy and reliability, especially, associated with a comparatively large approaching speed. In addition, from the discussions on the generation mechanism of the periodic error and high-frequency undulation, some worthwhile references to engineering applications are also derived.
