Patent ID: 8218153

Claim:
An optical measurement system for measuring a surface of an object, comprising: a definer for defining a radiation plane, in order to generate a measuring strip on the surface of the object; a matrix sensor with a resolution limited in a quantization direction by quantization, in order to acquire real mapping locations of the measuring strip on the sensor in the quantization direction and a direction perpendicular thereto, by making a capture of the measurement strip generated on the surface, wherein height information is determined on the surface of the object in the quantization direction, and the radiation plane is geometrically arranged with respect to the quantization direction so that real mapping locations on the sensor adjacent to each other in the direction perpendicular to the quantization direction correspond to different height information on the surface of the object; an evaluator formed to acquire an effective mapping location in quantization direction on the basis of the associated real mapping location and at least one further real mapping location adjacent to the associated real mapping location in the direction perpendicular to the quantization direction; and a resolution improver formed to increase a height resolution of the optical measurement system by varying an angle between a mapping direction of the measurement strip on the sensor and the quantization direction.
