    Abstract: A scanning system device has a predetermined aberration as it scans or switches light along selected optical paths. A deformable membrane receives the light and introduces an inverse “aberration” that offsets that of the scanning system. In one embodiment the scanning system includes a torsion arm that supports an oscillatory body. The torsion arm and/or body can be machined from metal, micromachined in silicon or formed in a variety of other ways. Alternatively, the scanning system may include a rotating polygonal scanner or other type of optical scanner. In another approach, an optical switch replaces the scanner.

    Abstract: An image capture device includes provision for projecting indicia onto an object surface. For a scanned beam image capture device, the image may be projected from the scan engine. The light source includes provision for modulating the intensity of its output. A controller modulates the output of the light source according to its position, forming a projected pattern. When the image capture device is an indicia reader such as a linear or 2D bar code scanner, the results of a decode attempt may be used to determine the contents of projected information. When a “no decode” is returned, the user may be prompted to scan again. When a decoded symbol includes directly useful data, all or a portion of the data may be projected. When the data refers to a look-up table, information from the look-up table may be projected. The device may additionally project finder patterns to aid aiming.

    Abstract: An image projection system includes an image generator and first and second projection screens. The image generator respectively generates the first and second portions of the image on the first and second projection screens. The first projection screen projects the first portion of the image in a first color, and the second projection screen projects the second portion of the image in a second color. Such an image projection system is often less complex and less expensive than a conventional image projection system such as a projection television system. In addition, such a projection system often provides a higher-quality image than a conventional image projection system.
