Abstract

The aligning device has a receiver receiving a part of the laser light reflected from a target, and delivering a reception signal. A guide is placed in the laser beam path. An evaluator derives a guiding signal from the received signal and applies it to the guide so that the laser beam is continuously directed to the target. The guide is a mirror (3) supported by a hinged (40) and two piezoelectric components (41, 42). They form, with the hinged (40), an orthogonal axes system for the mirror tilting. The evaluator comprises a computer which derives from the received signal a first guiding signal applied to a first component (41), and a second guiding signal applied to the second component (42).
