ABSTRACT:
The invention provides for an optical sensing arrangement for use in a mobile telephone. The sensing arrangement allows the telephone to decode tags of coded data printed on media present in internal and external pathways of the telephone. The sensing arrangement includes a beam splitter configured to deflect incoming light onto an image sensor of the telephone. The arrangement also includes a first infrared LED operatively directing light onto media present in the external pathway, with a filter and lens arrangement configured to receive and direct light reflected from the external media onto the beam splitter. Also included is a second infrared LED operatively directing light onto media present in the internal pathway, with a mirror arrangement configured to direct light reflected from the internal media into the beam splitter.
