Abstract: A laser light projection apparatus is provided for projecting laser light onto the surface of a target object. The laser light projection apparatus includes a laser light source that generates laser light and a housing with a cavity therein defined by sidewalls, at least a portion of which have one or more reflective surfaces. The cavity extends along a center axis of the laser light and has a first portion at which a distance between opposing sidewalls is less than a distance between opposing sidewalls at a second portion of the cavity at a distance farther from the laser light source than the first portion. At least a portion of the laser light generated by the laser light source is reflected from the reflective surface of the sidewalls to form a two-dimensional pattern spaced apart from the center axis.

Abstract: A system and method of imaging barcodes may include generating a first light beam from an illumination surface having first dimensions. The first light beam may be directed into an input aperture of an optical component to form a second light beam. The input aperture has second dimensions, where the first dimensions are at least as large as the second dimensions. The second light beam having irradiation spatially distributed across the second light beam may be projected to read a machine-readable indicia.

Abstract: The present disclosure relates to data readers including an improved imaging system that optimizes active and passive autofocus techniques for improving data reading functions. In an example, the data reader initially uses active autofocus techniques to focus a lens system based on a measurement reading by a rangefinder and acquire an image of an item in the field-of-view of the data reader. The data reader includes a decoding engine operable to decode an optical code of the item using the acquired image. If the decoding engine is unable to decode the optical code using the active autofocus technique, the data reader alternates to a passive autofocus technique to alter the focus settings of the lens system and reattempt the decoding process.
