ABSTRACT:
A machine-readable symbol reader includes a microfluidic lens assembly providing responsive, reliable auto-focus functionality. A range finder may provide distance to a planar target (e.g., barcode symbol) information for use in auto-focusing, with or without localization. Illumination system, if included, is selectively controlled based on the distance to target and auto-focusing functionality to substantially reduce power consumption. The localization may color optical sensors.
