A system and method for projecting coherent light with reduced diffraction pattern may include a coherent illumination source, structure with an aperture, and focusing lens. The focusing lens may have an object plane defined between the illumination source and structure, such that an illumination signal, such as an indication signal (e.g., green spot, aiming signal, etc.) that is projected through the aperture and onto an image plane does not exhibit a noticeable diffraction pattern, thereby having sharper edges and more perceptible to a user of a system that performs the projection of coherent light. The focusing lens may be in front of, at, integrated with, or behind the structure with the aperture, but the object plane remains between the coherent illumination source and structure with the aperture.

A code reader comprises a first imager and a second imager configured to capture an image with different field of views, a first illuminator and a second illuminator configured to project a different illumination pattern, and a processor operably coupled to the imagers and the illuminators. The processor configured to activate the first imager and the first illuminator as a receiver pair responsive to detecting a first condition, activate the second imager and the second illuminator as a receiver pair responsive to detecting a second condition, and decode an optical code using an image captured by the selected receiver pair.

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.

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.

The disclosure relates to a light sensor system for determining the proximity of electronic devices by analyzing the polarization of detected light. The light sensor system includes a plurality of light sensors each including polarizers, such as linear plane polarizers and/or circular polarizers. The filtered light sensors are each operable to detect light passing through the respective polarizers. The light sensor system further includes an unfiltered light sensor operable to detect the presence of light. The light sensor system includes a processor in operable communication with each of the light sensors, the processor operable to determine whether the detected light is polarized or non-polarized based on the accumulated data of the various polarized light sensors and unfiltered light sensor.

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.
