A sensor device (), for measuring a surface (), includes a lighting device () emitting a light beam (); an optical device () splitting the light beam () into partial light beams (), and emitting the first partial light beam () toward a first surface area () and emitting the second partial light beam () toward a second surface area (). A light sensor () is configured to receive a first surface area reflection (-) of the first partial light beam () and a second surface area reflection (-) of the second partial light beam (). A processor () is configured to detect a distance of the first surface area () and of the second surface area () to the sensor device () based on a position of the first partial light beam reflection (-) and the second partial light beam reflection (-) on the light sensor ().

Sensor device for measuring a surface

A light section sensor for providing an output of a digital output coordinate has an illuminating device for projecting a light line onto a measured object and an electronic camera for detecting the projected light line on the measured object. A processing device determines at least one measured coordinate in a measured coordinate system on the basis of the light line detected. A coordinate transformation device transforms the measured coordinates from the measured coordinate system into the output coordinates in an output coordinate system by a coordinate transformation. A slope angle determination device determines the slope angle of the light section sensor in relation to a flat surface of the measured object.

Light section sensor

A method and a device for the optical distance measurement and for the optical detection of objects with an at least partially specular reflective surface () wherein light through the specular reflective surface () and a diffuse scattering at a reflector () is directed to light receiving means and detected there.
