1. A retroreflective device for electro-optically reading a bar code symbol, comprising:

  • a) a linear array of light emitters for emitting light;

    b) a scanner for scanning the light across the symbol along a scan direction for reflection from the symbol;

    c) a collector for collecting light reflected from the symbol; and

    d) a linear array of detectors parallel to the linear array of emitters, for detecting the light collected by the collector over a field of view, and for generating an electrical signal representing the symbol.
