Abstract

A sensor device (100) comprises an emitter device (106) arranged to emit electromagnetic radiation and having an emission region associated therewith. The sensor device (100) also comprises a detector device (108) arranged to receive electromagnetic radiation and having a detection region associated therewith, and an optical system (122). The emission region is spaced at a predetermined distance from the detection region. The optical system (122) 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.
