The diffractive optical element (DOE) is always modeled as an ideal pure diffractive element which neglects the refractive dispersion of the element's material. In this paper a new model of the diffractive optical element is proposed in which the effect of the refractive dispersion of the DOE's material is considered. The new model is explained and compared with standard diffraction-order expansion with the help of a hybrid system example. The analytical results show that the new model has an important meaning for the exact analysis of the hybrid refractive-diffractive optical system. 2008 Copyright SPIE - The International Society for Optical Engineering.

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.

High energy lasers processing of materials is knowing an increasing interest since it not only can make manufacturing faster cleaner and more accurate but also because it opens up entirely new technologies and manufacturing methods that are simply not available by using standard techniques. In this paper an experimental set-up based on pulsed KrF excimer Laser assembled for surface patterning of mono and two-dimensional (1D-2D) micro and submicro structures on LiNbO3(LN) crystal will be described in detail. The apparatus has been used to produce photonic structures in LN both by patterning of PMMA photoresist and by direct surface patterning through laser ablation or direct laser writing. The structures and properties of the photonic crystals fabricated by using this apparatus have been investigated and the preliminary results will be presented.

Industries from agriculture to petrochemistry have found near infrared (NIR) spectroscopic analysis useful for quality control and quantitative analysis of materials and products. The general chemical polymer chemistry petrochemistry agriculture food and textile industries are currently using NIR spectroscopic methods for analysis. In this study we developed a new sort NIR instrument for food measuring. The instrument consists of a light source 12 filters to the prismatic part. The special part is that we use a mirror to get two beams of light. And two PbS detectors were used. One detector collected the radiation of one light beam directly and the value was set as the standard instead the standard white surface. Another light beam irradiate the sample surface and the diffuse light was collected by another detector. The value of the two detectors was compared and the absorbency was computed. We tested the performance of the NIR instrument in determining the protein and fat content of milk powder. The calibration showed the accuracy of the instrument in practice.
