Optical reading head with angled array

An optical reading head comprising:

• a plurality of light emitting devices comprising an array formed on an optically transparent substrate, the substrate having a first surface and a second surface, wherein the first surface and the second surface are joined, and wherein the first surface of the optically transparent substrate defines a normal plane and the second surface of the optically transparent substrate defines another plane set at an angle at which the plurality of light emitting devices are positioned, thereby positioning the plurality of light emitting devices for emitting of light toward an image that reflects a portion of the emitted light back towards the optically transparent substrate;
• and
• a detecting device located in a plane normal to the angled light emitting array that captures light reflected from the image toward the optically transparent substrate, thereby sensing the reflected light.
