Title: The Innovations of Erwin Spanner

Introduction

Erwin Spanner is a notable inventor based in Traunstein, Germany. He has made significant contributions to the field of optical measurement technology, holding a total of 17 patents. His work has advanced the understanding and application of optical position measuring devices and interferometers.

Latest Patents

One of Spanner's latest patents is an optical position measuring device. This device is designed to detect the relative position of two measuring standards that move relative to each other. It utilizes a splitting grating to divide a beam emitted by a light source into at least two partial beam bundles. These bundles undergo different polarization-optical effects as they travel through scanning beam paths. After recombination at a combination grating, the device generates multiple phase-displaced, displacement-dependent scanning signals. Notably, no polarization-optical components are placed in the scanning beam paths between the splitting and recombination stages.

Another significant patent is for an interferometer that includes a light source and a beam splitter. This interferometer splits the emitted beam into a measurement beam and a reference beam. The measurement beam travels through a measuring arm to a measuring reflector, which creates an offset perpendicular to the direction of incidence. The reference beam travels through a reference arm to a reference reflector. The interferometer is equipped with a detector system that generates a distance-dependent interference signal based on the position of the measuring reflector.
