20080198367 | Interferometric System for Complex Image Extraction - The invention provides an interferometric system and method for quadrature detection of optical characteristics of a sample. The system includes a Mach-Zehnder interferometer providing a variable optical delay between light collected from the sample and reference light. The Mach-Zehnder interferometer has an output M×N coupler with N≧3 output ports. Two differential detectors, each having two input ports coupled to a different two of the N output ports of the M×N coupler, produce first and second electrical signals having an interferometric phase shift. A processor is provided for computing real and imaginary parts of a complex refractive index of the sample from the first and second electrical signals by using complex deconvolution. | 08-21-2008 |

20140294527 | TOOL HEAD AND METHOD FOR MACHINING A METALLIC WORKPIECE - A tool head includes an ovoid basic element disposed about a center axis, at least two chip grooves formed in the basic element, and a number of major cutting edges. Each major cutting edge is disposed in a convex course along a respective chip groove of the at least two chip grooves. The major cutting edges define with their radially outermost region a nominal diameter. A radial distance from each major cutting edge to the center axis in a front, tip-side, arc portion increases up to the nominal diameter and in a rear, shank-side, arc portion decreases back down to a minimum diameter. | 10-02-2014 |
