Abstract:
An apparatus measuring optical characteristics including position detection is disclosed. A processor is coupled to a display. A first optical sensor makes a first measurement, and a second optical sensor makes a second measurement. A source of illumination and the first optical sensor determine a minimal distance between the apparatus and an external object such that illumination emitted by the source is not received by the first optical sensor when the apparatus is less than the minimal distance from the external object. A position of the apparatus with respect to an object and an optical property of light received by the apparatus are determined. A transparent member with a thickness less than the minimal distance may provide illumination external to the apparatus and receive light from external to the apparatus.
