US Patent:

6568598, May 27, 2003

Filed:

May 13, 1998

Appl. No.:

09/078196

Inventors:

Mohan LeeLaRama Bobba - Eugene OR
Jorge Luis Acosta - Eugene OR
Timothy Joseph Eusterman - Plano TX
James W. Ring - Eugene OR
Alexander McQueen - Eugene OR

Assignee:

PSC Scanning, Inc. - Eugene OR

International Classification:

G02B 2612

US Classification:

23546239, 23546736

Abstract:

An optical system and method for data reading. The preferred system is directed to a scanner which includes a multiple beam source such as a laser diode and a beam splitter which generates 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 is 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 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 the bottom and all lateral sides of an object being passed through the scan volume.
