Laser-Marking and Calibration
Laser technology enables extremely fast product marking and electronic devices calibration, for example LED brightness calibration for car vehicle lights. The laser is controlled by a DSP system with stringent real-time requirements, since delays or jitter will inevitably cause failures and inconsistencies. Matrix and vector calculus is used to control laser intensity deflectors.
Piezo Drive Controller
Piezo drives are used for high resolution positioning in 3D-lithography. Capacitive sensors and strain gauges are used for positional feedback. The servo control must be extremely fast and requires high resolution A/D converters. DSPs are capable of sustaining the high sampling rates, they apply linearization and corrections and control the piezo drive.
