1. An optical vehicle laser sensor system for detection of vehicle dynamics parameters, comprisinga laser device for generating at least one laser beam, so that said laser beam generates a laser spot on a reference surface placed opposite to the laser device,an imaging device comprising at least one matrix sensor with a lens for imaging said laser spot onto said reference surface, said imaging device being arranged so that said laser spot onto said reference surface is visible within a field of view (40) of said imaging device, whereby the optical axis of said imaging device and the direction of said laser beam are non-coincident,a detector for detecting a velocity of said optical vehicle laser sensor system relatively to said reference surface from the signal of said laser beam reflected or scattered back from said reference surface,a data processing device for detecting the laser spot location within the image data retrieved from said imaging device, and calculating the orientation of said optical vehicle laser sensor system from the spot location.
