Abstract
The present disclosure concerns a device for distance measurement for a laser processing system. The device comprises a light source, which is configured to generate a primary beam for direction onto a workpiece, at least one detection device configured to record a secondary beam reflected from the workpiece, at least one optical amplifier configured to amplify the primary beam and/or the secondary beam, and an evaluation unit configured to evaluate interference between spectral components in the frequency domain.
