Beschreibung
Zusammenfassung:	A driver assistance system (106) of a vehicle (100) includes a laser scanner (101) with a phase-controlled laser (102), a sensor unit (104) and an evaluation unit (103). The phase-controlled laser is configured to produce a controllable laser beam by beam forming and to direct the laser beam into an environment outside of the vehicle. The sensor unit (104) is configured to detect a retroreflection caused by the laser beam. The evaluation unit (103) produces driver assistance data by evaluating the detected retroreflection.
