Operating principle of laser beam-riding guidance was set forth. Based on the principle of spatial frequency-encoding
experimental results demonstrated that the receiver can receive correctly the encoded signal and can decode the signal
an optimum laser encoding mode was designed
measurement for the missdistance is feasible and all the performance parameters satisfy the demand. (2012) Trans Tech Publications
which can transfer continuous laser into pulse laser that represents different position information. Then the mathematic model of deviation from target is built
Switzerland.
a modified encoding pattern was presented
which is composed of two light paths crossed 90. Azimuth information of target is given in orthogonal coordinate system and deviation from target is linearity. As well as
characteristic distribution of spatial laser field is analyzed. Corresponding decoding mode was presented
by testing in 2 kilometers outdoor

In ultraviolet spectroscopy
groove irregularity and surface roughness of nanometer magnitude can cause a significant loss of diffraction efficiency. Therefore
there is a constant need to improve the diffraction efficiency. A blazed grating can concentrate most of the light intensity into a desired diffraction order
it is important to control the groove shape precisely
so it is the optimum choice among gratings of different kinds of profile. As the operating wavelength of most UV spectral applications is less than 200 nm
especially the blaze angle and the apical angle. We have presented a direct shaping method to fabricate EUV blazed gratings by using an ion-beam mixture of Ar+ and CHF2 +to etch K9 glass with a rectangular photoresist mask. With this method
the required blaze angle is small
we have succeeded in fabricating well-shaped UV blazed gratings with a 1200 line/mm groove density and 8.54 blaze angles and 1200 line/mm groove density and 11.68 blaze angles
and the metrical efficiency is about 81% and 78%. The good performance of the gratings was verified by diffraction efficiency measurements. When one uses the etching model
the conditions on the ion-beam grazing incident angle and the CHF3partial pressure should be noted. Besides
since the etched groove shape depends on the aspect ratio of the photoresist mask ridge
if we wish to fabricate larger gratings with this method
we must improve the uniformity of the photoresist mask before ion-beam etching. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

Mathematical models of structural optimization were established for the cam wave generator
then a conceptual model
by integrally taking its static and dynamic performance into consideration
which satisfied the model acted by four concentrated forces
while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method
was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3
which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously
the static analysis and modal analysis were implemented
and the results show that the static and dynamic performance complies with the design requirements
proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator
but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.

A new particle filter-the Local Optimum Particle Filter (LOPF) algorithm is presented for tracking object accurately and steadily in visual sequences in real time which is a challenge task in computer vision field. In order to using the particles efficiently
we first use Sobel algorithm to extract the profile of the object. Then
we employ a new Local Optimum algorithm to auto-initialize some certain number of particles from these edge points as centre of the particles. The main advantage we do this in stead of selecting particles randomly in conventional particle filter is that we can pay more attentions on these more important optimum candidates and reduce the unnecessary calculation on those negligible ones
in addition we can overcome the conventional degeneracy phenomenon in a way and decrease the computational costs. Otherwise
the threshold is a key factor that affecting the results very much. So here we adapt an adaptive threshold choosing method to get the optimal Sobel result. The dissimilarities between the target model and the target candidates are expressed by a metric derived from the Bhattacharyya coefficient. Here
we use both the counter cue to select the particles and the color cur to describe the targets as the mixture target model. The effectiveness of our scheme is demonstrated by real visual tracking experiments. Results from simulations and experiments with real video data show the improved performance of the proposed algorithm when compared with that of the standard particle filter. The superior performance is evident when the target encountering the occlusion in real video where the standard particle filter usually fails.
