Abstract:
A proximity sensor includes a radiation source configured to emit a primary radiation beam and a primary detector configured to pick up a reflected primary radiation beam. The radiation source is further configured to emit stray radiation. The sensor further includes a reference detector arranged to receive the stray radiation. The stray radiation may, for example, be emitted from either a side of the radiation source or a bottom of the radiation source.
