Relative speed sensor unit for machine tools and printing machines has detectors measuring light pulses with set decay time |
| 摘要 |
A relative speed sensor unit has a moving sensor head (1) emitting light pulses (1.1) with a set decay time that is detected by fixed (2) detectors (1.2, 1.3) and differenced (3.1) or divided to measure (3) relative speed and acceleration in two dimensions.
