Abstract: A 2D bar code reader with improved motion tolerance is presented. The 2D bar code reader includes a lens configuration that enhances chromatic aberration to separate the focal planes on which bar code images from two different color components of a light will be focused. An imager interprets one of the focal planes as the image and the other one as noise to be ignored. In addition, the increased depth of field generated by the chromatic aberration allows for a larger aperture stop setting and quicker shutter speed, thereby improving motion tolerance.

Abstract: An automatic data collection device, such as a scanner-type device, is provided with an afocal optical element, such as an afocal lens, that operates in conjunction with a scanning mirror to scan a target machine-readable symbol using a scanning beam. The scanning mirror deflects a light beam into the afocal lens. The afocal lens operates to change a resolution or width of the scanning beam for far-field scanning, for example, where resolution is increased by the afocal lens. The afocal lens can also operate to change the resolution or width of the scanning beam for near-field scanning, for example, where resolution is decreased by the afocal lens.

Abstract: An automatic data collection device, such as a scanner-type device, is provided with a deformable mirror that operates in conjunction with a scanning mirror to scan a target machine-readable symbol using a scanning beam. The deformable mirror includes a reflective membrane having a shape that can be changed by applying electric charge to conductors, or by some other type of actuation. In this manner, the focus distance, depth of field, wavefront shape, or other property of the scanning beam can be changed dynamically. Feedback information can be provided to a focus control algorithm to control adjustment of the deformable mirror so as to optimize the scanning.
