Dynamic Air Turbulence Compensation for Laser Measurement Apparatus

Measurement apparatus comprising a laser measuring system an acoustic system is described. The apparatus provides a feedback control signal that can be used in the feedback control system of an associated machine. To allow real time, dynamic, operation the laser measurements are compensated using a...

Beschreibung
Zusammenfassung:	Measurement apparatus comprising a laser measuring system an acoustic system is described. The apparatus provides a feedback control signal that can be used in the feedback control system of an associated machine. To allow real time, dynamic, operation the laser measurements are compensated using a compensation value derived from a plurality of laser measurements and at least one acoustic time of flight value.
