      Description

      A new development for Surface & Geometric Dimensioning and Tolerancing (GDT) measurements;
      Current instruments widely in use are Coordinate Measurement Machines (CMM) which are very time consuming, e.g. time for a car door measurement may take up between 6 to 8 Hrs.;
      Our equipment will do the same measurement for the same object in less than 20 seconds;
      We have reached production practice. All future changes are mainly Software related only, e.g. “tweaking measurement time”.

      The market, Aero, Military, Automotive etc. needs Equipment which will Measure accurately from the smallest part to the largest panel continuously in a assembly line, e.g. CMM’s cannot provide this;
      Our Scanning Equipment can be integrated in a manufacturing line and measure parts faster and more economical than machines in use.
      This will save on expenditures, increase overall Product Quality and Profits

      The technology is a powerful system using building blocks and a new technology based on a photogrammetric approach to recover three-dimensional information.
      The Scanner is using „Building Blocks“. It is possible to serialize or parallelize several single scanner into one sizeable scanner matrix which allows for large surfaces to be measured.
      Therefore the measurement and analysis of large point clouds towards measurement results against CAD data will be much faster and more accurate.

            Preview
            Description

            This novel invention uses polishing techniques to slowly polish or abrade away stepped layers of an object to be scanned. The scanned object is cast into a contrasting resin which provides a dark (or light) background for photography. The layers are digitally photographed stepwise to produce a record of internal structures. 2D digital images are reassembled using computer and software methods to produce exquisitely fine detailed 3D digital models of the solid internal structures in full color.

            Because polishing can be controlled tightly, layers may be removed in the in the nanometer realm. This implies the limiting barrier in resolution is the pixel size of the recording camera. These cameras pixels are getting denser and denser as technology progresses which only improves the performance of the 3D scanner.

            The multi-spectral light used to illuminate the image plane can be used to identify the chemical components of the object. Therefore the 3D scanner has a spectrometer function as well.

            The Full Color 3D Solid Image Scanner would be important in the semiconductor industry. Most importantly 1st article scanning semiconductor devices to determine as manufactured state vs. as designed.

              Description

              People are always amazed by the development of optical communication. Things move really fast in this industry. Fiber optic transceiver, a small-size but important optical component, can best represent the advancing of the optical communication industry. The form factor of optical transceivers has changed from GBIC for Gigabit Ethernet to SFP+ for 10GbE, QSFP+ for 40GbE and 100G CFP and QSFP28. Even a double density QSFP—QSFP-DD for 200/400GbE is under research. It’s not difficult to recognize all these different types of fiber optic transceivers. However, customer could be confused about how to connect these transceiver to the telecommunication network. This post will introduce how to select patch cables for optical transceivers in details.

              Patch Cable Selection Guide
              To select the right patch cable for your modules, you should firstly have a comprehensive understanding of the modules mainly from the following aspects: transmission media, interface, transmission distances and data rate.

                    Description

                    DESCRIPTION
                    The present invention relates to a method and a device to measure the circular dichroism exploiting a diffraction grating with proper polarization properties.
                    The grating generates first orders diffraction beams whose amplitudes are proportional to the left and right circular components of the incident light beam. We demonstrate that, exploiting this feature of the grating, the circular dichroism of any system can be easily evaluated measuring only the intensities of the first order diffracted beams, just locating the grating after the investigated system.

                    -The dispersive properties of the grating allow to perform real time measurements, since the signal at any wavelength is diffracted at different angles from the grating and can be revealed in parallel by a photodiode array or a CCD;
