摘要： An optical system and method for data reading. A preferred system is directed to a scanner which includes a laser diode and a beam splitter for generating first optical beam and a second optical beam, the first optical beam being directed toward one side of a scanning optical element such as a rotating polygon mirror and to a first mirror array, the second optical beam being simultaneously directed toward a second optical element such as another side of the rotating polygon mirror and then to a second and a third mirror array. The first mirror array is configured to generate a scan pattern through a vertical window and the second and third mirror arrays are configured to generate scan patterns passing through a horizontal window. In combination, the three mirror arrays generate three sets of scan lines so as to scan five sides of a six-sided item (e.g., the bottom and all lateral sides of an object) being passed through the scan volume.
