Technical Examples

A Low-Cost Absolute Linear Optical Encoder ("LALOE") for determining the absolute position of a read-head within the LALOE relative to a codestrip is disclosed. The LALOE may include an emitter module within the read-head, the emitter module having a plurality of light sources arranged in an light source pattern and a 90Â° Out-Of-Phase light source; and a detector module within the read-head, the detector module having a plurality of photo-detectors arranged in a photo-detector pattern corresponding to the light source pattern and a 90Â° Out-Of-Phase photo-detector corresponding to the 90Â° Out-Of-Phase light source.
