            • Full Color 3D Solid Image ScannerFull Color 3D Solid Image Scanner

                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.

              • Continuous flexible process control via 3D surface and geometry measurements in productionContinuous flexible process control via 3D...

                  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.
