Latest Patents

Walburga Kern holds 1 patent for her invention of a photoelectric position measuring device. This device features a scale that is designed as a phase grating. In this system, several partial beams impinge on the scale, where they are diffracted and cause interference within the scanning unit. The entry angle of the partial beams corresponds to the Littrow angle, ensuring that the diffracted partial beams of ±1st diffraction order are diffracted at the same angle. The diffraction efficiency of the scale is optimized when the flanks of the bars are angled at approximately 70 degrees relative to the measuring direction, resulting in trapezoidal cross-sections for the bars and gaps.
