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.

Abstract: An image system includes a screen and a beam generator. The screen has first and second regions with adjustable brightness levels. The beam generator directs first and second electromagnetic off beams and first and second electromagnetic on beams onto the first and second regions, respectively. The first and second off beams respectively change the brightness levels of the first and second regions according to a first polarity, and the first and second on beams change the brightness levels of the first and second regions according to a second polarity. For example, the system may simultaneously scan multiple tiles of an image onto respective regions of the display screen with respective image (on) beams, and erase the regions with respective erase (off) beams. Scanning an image as multiple tiles often provides the image with a higher resolution for a given scan rate, and using on and off beams often increases the quality of the image.

Abstract: An optical image system includes an image projector and an image generator. The image projector has regions with adjustable brightness levels. The image generator generates an image received from a remote location on the image projector by directing first and second electromagnetic beams onto the regions of the image projector. The first beam changes the brightness levels of the regions in a direction, and the second beam generates the image by changing the brightness levels of predetermined ones of the regions in an opposite direction. Such an image system can capture, transmit, and display an image using an optical signal without converting the optical signal into an electrical signal and back again. Thus, the image system often provides a higher-quality image than conventional electro/optical image systems.

Abstract: A scanning control circuit generates a clock signal corresponding to an expected scan timing of a resonant scanner. In one approach, the control circuit uses a pair of direct digital synthesis (DDS) integrated circuits. A first DDS chip provides a system clock that is synchronized to the monitored period of the scanner. A second DDS chip generates a frequency chirped signal that has a frequency profile corresponding to a desired pixel clock timing. To control phase precisely, four complementary clock signals are weighted and mixed at light source drivers to produce relative phase shifts for different light sources.

Abstract: A display apparatus includes a scanning assembly that scans about two or more axes, typically in a raster pattern. A light source emits light toward the scanning assembly such that the scanning assembly simultaneously scans more than one of the beams. The light source is positioned such that its beam illuminates a discrete region of the image field. The image may be formed from a set of “tiles” where a single sweep of the scanning assembly scans a plurality of beams simultaneously. Various approaches to controlling the intensity of the light to compensate for variations in light source response or optical system response, or to balance the response of a tiles system are described. Among these approaches are scaling data in a buffer, active multiplication, or control of a D/A converter.

Abstract: An image system includes a beam generator and a screen having a region with an adjustable brightness. The beam generator directs first and second electromagnetic beams onto the region. The first beam changes the brightness of the region according to a first polarity and the second beam changes the brightness of the region according to a second polarity. Such an imaging system can generate a video frame on a projection screen such that each pixel of the frame is “on” for the same or approximately the same amount of time as each of the other pixels. This technique prevents portions of the image from appearing visibly dimmer than other portions. It also allows the persistence of the screen regions to be relatively long, e.g., longer than the frame rate, and thus allows the screen to display/project relatively high-quality video frames.

Abstract: A display apparatus includes an image source that scans about two axes. To offset motion about a first of the axes during sweeps about the second axis, the apparatus includes a structure to produce offsetting motion about the first axis at a scanning rate equal to the twice-scanning rate about the second axis. The offsetting scan can be a ramp or other motion. In one embodiment, the offsetting motion is a resonant sinusoid. The offsetting motion may be produced by an auxiliary scanner such as a mechanical scanner, a piezoelectric scanner, a MEMs scanner or other scanner. Because the offsetting motion is very small, the auxiliary scanner can function with a very small scan angle.
