A remote robot control system was introduced, which is based on RIA (Rich Internet Application) technology and Flex platform. The system is comprised of two parts, which are the robot control module and the design module for foreground Web page application. This paper introduced the functions of each sub block, as well as the design of the programs. Meanwhile, the construction of the whole Web Service system has been specifically outlined. By using Flex technology, the system realized an asynchronous communication between Web and Web Service components, so that the real-time capacity has been greatly enhanced. © (2011) Trans Tech Publications, Switzerland.

A new simultaneous measurement system of displacement and angle is designed to compensate for Abbe declination error caused by cantilever movement. First, based on the theory of laser interference, the angle is converted to the displacement which can reflect the change of optical path difference in the interference system, by changing the path. Second, interference fringes will produce steady periodicity movement by promoting the flexure hinge with piezoelectric ceramics (PZT). Finally, the method of 4-fold-frequency subdivision and direction judgment is adopted, and the experiment on the receiving and processing of dynamic fringes is conducted. The experimental result shows that with an appropriate fringe width, the system can meet the requirement for the precision measurement of Abbe declination.

A displacement sensor with controlled measuring force and its characteristics analysis are discussed in this paper. The displacement sensor consists of an electric induction transducer with high resolution and a voice coil motor (VCM). The measuring principles, structure of the sensor are discussed. Theory model, dynamic and static characteristics of VCM are analysed. A measuring system for surface topography with large measuring range is constructed based on the displacement sensor and 2D moving platform. Measuring force of the sensor in measurement process of surface topography can be controlled at μN level and hardly changes. It has been used in measurement of bearing ball,bullet mark, etc.

In order to improve the accuracy of measurement result of optical lenses with large depth of field in industrial visual inspection, image restoration must be carried out on the intermediate image in order to obtain a more accurate measurement result, and the point spread function (PSF) is the key to the image restoration. Non-diffracting imaging system was designed according to the formula of maximum non-diffracting distance of axicon, based on the scalar diffraction theory, PSF of the system was theoretically deduced by the stationary phase method within frequency range. Using the theory of quasi monochromatic light, the relationship between the PSF and the axicon angle or defocus was analyzed under incoherent light illumination. Simulations and experimental results show that the intensity of central spot of PSF is stronger and the density of diffraction fringes is larger when the refracting angle increases, while the influence of defocus on PSF has an opposite effect.
