AI Technical Summary
Optical measurement of gear teeth is challenging due to their geometry, high reflectivity, and environmental factors like contamination, vibrations, and temperature fluctuations, which complicate achieving optimal probing angles and affect measurement accuracy and reproducibility.
A coordinate measuring machine equipped with an optical distance sensor and a light source that includes a broadband light-emitting material, active temperature control, and active light intensity control, combined with a light guide and optics, to provide a stable and spectrally homogeneous light source for improved gear measurement.
The solution achieves improved measurement accuracy and reproducibility in optical gear measurement by ensuring a stable, broadband, and spectrally homogeneous light source, enhancing the measurement speed and quality.
