摘要：
A wavelength selector in an optical scanner is operative for selecting a first laser beam having a predetermined wavelength to produce a first scan pattern, and for selecting a second laser beam having a different wavelength to produce a second scan pattern. The scan patterns have a different number of scan lines. The selected scan pattern is scanned over indicia, e.g., a bar code symbol, to be read.
