A dual aperture optical scanner as mentioned in this paper produces horizontal, vertical, and diagonal scan patterns with a plurality of pattern mirrors reflecting the first group of scanning beams in a substantially horizontal direction through the first aperture.Abstract:
A dual aperture optical scanner which produces horizontal, vertical, and diagonal scan patterns. The optical scanner includes a housing having a substantially vertical surface containing a first aperture and a substantially horizontal surface containing a second aperture. A laser diode produces a laser beam. A spinner produces first, second, and third groups of scanning beams. A plurality of pattern mirrors reflects the first group of scanning beams in a substantially horizontal direction through the first aperture, the second group of scanning beams in a substantially downward diagonal direction through the first aperture, and the third group of scanning beams in a substantially vertical direction through the second aperture.read more

Omnidirectional laser scanning bar code symbol reader generating a laser scanning pattern with a highly non-uniform scan density with respect to line orientation
TL;DR: An improved laser scanning system is provided employing multiple off-center lasers and an irregular multi-sided scanning polygon, producing a laser scanning raster over a total sweep of approximately 180 degrees of polygon rotation as mentioned in this paper.
Patent
Method of and apparatus for multiplying raster scanning lines by modulating a multi-cavity laser diode
TL;DR: In this article, a method of and apparatus for generating a multiple raster-type scanning pattern by modulating a multi-cavity laser diode in such a way that it sequentially generates different laser beams synchronously during different laser scanning cycles, while the output laser beams are directed incident upon a rotating polygonal laser scanning element.

Bioptical laser scanning system providing 360° of omnidirectional bar code symbol scanning coverage at point of sale station
TL;DR: In this paper, a bioptical laser scanning system employing a plurality of laser scanning stations about a two independently controlled rotating polygonal mirrors is described. But the system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation.
