Abstract
A system for optically reading an encoded pattern on a patterned test strip or other patterned target placed in proximity and moved with respect to an optical code reader. The reader can include an LED light source. A transmit baffle located between the LED light source and the target can define a transmit aperture for passing light originating from the LED light source to a target location on the patterned target. A photodetector arranged to receive light associated with the target location can produce a response signal providing information about the encoded pattern at the target location. A receive baffle located between the photodetector and the target can define a receive aperture for passing light from the target to the photodetector. Signal processing circuitry can be coupled to the photodetector to receive the response signal, and to decode information about the encoded pattern.
