Introduction

Thomas Kaelberer is a notable inventor based in Schrobenhausen, Germany. He has made significant contributions to the field of optical position measurement, holding a total of 10 patents. His work focuses on developing advanced devices that enhance precision in measuring relative positions.

Latest Patents

One of his latest patents is an optical position-measuring device designed to suppress disturbing higher diffraction orders. This innovative device includes a light source, scales, and a detector. The scales are movable relative to each other and are arranged in crossed relation, each featuring a graduation with periodically arranged grating regions that possess different optical properties. The illumination beam is split into sub-beams at the first scale, which then impinge on the second scale and are reflected back. The reflected sub-beams recombine at the first scale, generating a resulting signal beam that propagates toward the detector. This configuration allows for precise measurement while filtering out unwanted diffraction orders.

Another significant patent is an optical position measuring device that records the relative position of two scales. The scales are oriented parallel to specific measuring directions, creating a horizontal plane of movement. The light source emits an illumination beam that is split into sub-beam bundles, which then impinge on the second scale. This scale is tilted relative to the horizontal plane, allowing for back-reflection to the first scale, where the sub-beams are recombined. This process generates phase-shifted scanning signals that correspond to the relative movement of the scales.
