Methods in Solid Mechanics, Proc. A principal layout is on the figure1. This process is mainly used with a pulsed Nd: The result grating on the surface of the measured object or screen is recorded by the camera C. We generated the two-photon Werner states, which represent a smooth transition between maximally entangled singlet state, and maximally chaotic mixed two-photon state. The holographic element can be protected against moisture by means of a protective cover in order to stabilise the DCG layer.

Milburn, Quantum Optics Springer, Berlin,chap. Zeilinger, Nature Positions of minima of the behaviours in dependence on time elapsed from the moment of the end of the interference filter development are determined and analysed. SYSWELD allows user-defined weld sequencing and control of the weld manufacturing parameters such as velocity, energy input and many others. The setup and adjustment especially is much more difficult for the topographic measurement. The main disadvantage of the profilometry is the execution of the calibration which is necessary to be done in the measurement process.

But this protection changes input conditions for waves entering the element and increases losses of energy. The second one equals in intensity to the first one and represents conjugate image.

The characteristic of dichromated gelatin to be moisture sensitive gives ability of controlling spectral transmittance of the interference filters. The probability of pair creation is opptoelektronika low in common nonlinear materials so that traditionally the probability of generation of more than one pair in a single detection interval was optlelektronika. However it is necessary to pay close attention to the thermal expansivity and rigidity of the mechanism, because the system is very sensitive to misalign.

That means only the shape of contours can be determined. In bernaed case when we are interested in photon pairs situated close to the horizontal cross-section of the cone so that the curvature of the cone layer cross-section in the photocathode plane is negligible, the coordinates x, y can easily be related to radial qs, qI and angular fS, fI angles see Fig. The signal is digitized using a three-channel Licel transient recorder TR with beenard resolution at 40MHz sampling rate [3].

We can use this formula only for intensities that produce much fewer detections at the camera than the number of active pixels [20]. Although the computation of the profile is simpler then the applied image processing, it has to be performed for every measured profile on the other hand.

In particular, the attention will be paid to schemes implementing symmetric or asymetric clonning using unbalanced beam spliters. LIDAR has much usage in measuring technology, for example it is possible to locate defects or unhomogeneities optorlektronika optical fibers, to measure distance, speed, rotation, chemical composition and concentration of a remote optoelejtronika, where the target can be a sharp defined object, or a diffuse object such a cloud or atmosphere.

Zero order represents directly transmitted reconstruction wave. Automatic solution for welding and heat treatment problems was provided by the Bbernard solver, covering all related complex mathematics and material physics.

It creates the divergent beam. These profiles serve as the basis of the WRML model. For that purpose, we have found the method of maximum likelihood estimation extraordinarily suitable. This mirror reflects back the laser beam that interferes with the incident one. The two different approaches are possible to determine the shape of object zitel.

For these purposes the light grating projector was used. The projection of the light grating and the origin of the periodic structures are shown on the Fig. There are shown the temperature fields during welding and start of cooling with pre-defined conical heat source in the figure 4.

Annual fee is ,- CZK. The mesh defines the geometry of the structure, it contains some additional data like groups figure 2. Then the screen was removed and replaced by the measured object. They were extremely successful as a means to perform experiments confirming the fundamental laws of quantum mechanics [2].

From these analysis results, that weld metal has a bainitic structure, with a acicular orientation at the weld root. This numerical model was used mainly to set of the suitable process parameters, to determinate of the temperature field during laser welding and the range of molten zone and heat affected zone, but it provides instantaneous process information for the heating and cooling rates, metallurgical structure of the material, distortions, stresses, yield stress of the modified material, plastic strains, that is area of next research.

The areas that are detected by the camera are signed as As, AI.

Several views to the measured cotyle are illustrated hernard the Fig. Figure 5 shows the scheme of the setup with a Mach-Zehnder interferometer in the idler photon arm, and with an adjustable Fabry-Perot resonator in the signal photon arm.

Express 9, From the gradient of the curve it is obvious that the first photomultiplier catch the most part of the response to the beam. In this arrangement, a beam of high energy electrons went from the tail pipe of the LINAC and developped towards the calorimeter where it ootoelektronika absorbed. This is achieved using morphological bernar based on skeletonization. The task for fluorescence detectors is to detect the feeble fluorescence light emitted by nitrogen molecules excited by collision with cosmic rays of very high energy in high level atmosphere at the altitude up to 20 km.

Area of correlation of the correlated photon pairs is determined. Except the original gratings the other structure is observed on the result image. A 35, ; M. We show that even though the overall quantum efficiency of the intensified CCD camera is rather low compared to other photon-number resolving detectors, it is possible to directly measure the nonclassical character of the field as well as to reveal nonclassical features of the quantum state using reconstruction based on the maximum likelihood approach.

Spectral transmittances of the filter are detected in dependence on time elapsed from the moment of the end of the filter development. In heat conduction welding only the surface of the materials is melted. It may be mentioned that if the interference pattern is not recorded in depth, the hologram will be a thin hologram even if the emulsion is thick.
