Abstract
A sensor arrangement for a banknote validator or other document acceptor using optical transmissive measurements includes at least one light source located on a first side of a document path and arranged to transmit light around the document path to a second side of the document path, the second side being opposite the first side. Optical detectors are located on the first side of the document path and arranged to receive light sent from the light source and passing through the document transport path.
