Abstract

First and second light pointlike sources in a sensor device are positioned to illuminate an upper inside surface of a transparent layer so that light is totally reflected onto an image sensor. The image sensor is positioned so that light reflected from a utilized portion of the upper surface falls on the surface of the image sensor. The image sensor dimensions can be such that the image sensor receives light totally reflected from a first portion of the utilized portion in response light from the first light source, and receives light totally reflected from a second portion of the utilized portion in response light from the second light source.
