A sensor device () comprises an emitter device () arranged to emit electromagnetic radiation and having an emission region associated therewith. The sensor device () also comprises a detector device () arranged to receive electromagnetic radiation and having a detection region associated therewith, and an optical system (). The emission region is spaced at a predetermined distance from the detection region. The optical system () defines a plurality of principal rays, a number of the plurality of principal rays intersecting the detection region. The number of the plurality of principal rays also intersect the emission region.

Sensor device

A method for compensating range offset of a range sensor located in a predetermined position in a spatial environment and comprising a pixel array adapted for measuring a distance, the spatial environment comprising at least two stationary reference positions located at predetermined reference distances, the method comprising the steps of: a) determining distance values to the reference positions; b) calculating differences between the distance values and the corresponding reference distances; c) determining a range offset value as the maximum of the differences; d) measuring distance values to positions within the spatial environment using the pixel array; e) correcting the measured distance values by subtracting the determined in-situ range offset value from each of the measured distance values.
