Abstract
An apparatus for ascertaining a distance to an object has a light source unit for emitting an optical signal with a time-varying frequency, an evaluation device for ascertaining a distance to the object based on (a) a measurement signal that arose from the signal and was reflected at the object and (b) a reference signal that was not reflected at the object. The apparatus has also a dispersive element disposed in the signal path of the optical signal and an optical position sensor disposed downstream of this dispersive element in the signal path.
