A plurality of the areas of different light reflectivity of a bar code symbol, or the like, are simultaneously illuminated, using, e.g., a beam of laser light that has an elongated cross-section. The laser light beam is swept over the symbol in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time, until the symbol is read. The light that reflects from the illuminated region of the symbol is imaged on a linear sensor array, which is then scanned or read out to produce signals representative of spatial intensity variations of the imaged light along a linear path in the field of view.
A method for reading a symbol representing information having areas of different light reflectivity, comprising the steps of:
A method of reading with a hand-held reading device a two-dimensional bar code symbol having a plurality of ordered rows of bar coded information, each row extending generally along a longitudinal direction, said rows being successively arranged along a direction generally transverse to the longitudinal direction, comprising the steps of:
