摘要： An optical information detecting apparatus is formed as an integrated, solid state monolithic structure. The monolithic structure includes a plurality of light sensors disposed on a substrate and electrically isolated from one another, a plurality of light emitting elements disposed on the substrate and electrically isolated from one another, the light sensors being optically isolated from the light emitting elements, and a circuit connected to the light emitting elements to generate light towards a target and connected to the light sensors to detect reflected light from the target, wherein a signal is generated in response to the detected light. The signal is indicative of an optical characteristic of the target.

摘要： A scanner for scanning an item positioned in a scan volume can include: an electronically switchable mirror configured to switch between a reflective state and a transmissive state, a plurality of mirrors, and a camera having a sensor. In a method for scanning the item, the scanner can repeatedly: switch the switchable mirror from the reflective state to the transmissive state, image a first field of view of the item onto the sensor with light that reflects from at least one mirror and transmits through the switchable mirror, switch the switchable mirror from the transmissive state to the reflective state, and image a second field of view of the item onto the sensor with light that reflects from at least one mirror and reflects from the switchable mirror. In some examples, the scanner can synchronize the switching of the switchable mirror to a frame rate of the sensor.

摘要： A hand-supportable linear-type planar laser illumination and imaging (PLIIM) based device comprising a linear image formation and detection (IFD) module having a linear array of image detection elements and also image formation optics having a field of view (FOV) focusing a linear image of an object onto the linear array of image detection elements. A pair of planar laser illumination arrays (PLIAs) is arranged on opposite sides of the linear image formation and detection module, and produces a plurality of spatially-incoherent planar laser illumination beam (PLIB) components that are optically combined with respect to other PLIB components so as to produce a composite planar laser illumination beam (PLIB) that is arranged in a coplanar relationship with at least a portion of the FOV. Each PLIA includes a plurality of planar laser illumination modules (PLIMs). Each PLIM includes a laser diode and beam focusing and diverging optics for producing one spatially-incoherent PLIB component. The composite PLIB produces a number of substantially different individual speckle noise patterns at the linear array of image detection elements during the photo-integration time period thereof. The speckle noise power observed at the linear array of image detection elements is reduced through temporal averaging of the individual speckle noise patterns during the photo-integration time period. By virtue of the present invention, it is now possible to use visible laser diodes (VLDs) to produce speckle-reduced images of objects suitable for OCR processing, while enjoying improved working distances offered by planar laser illumination techniques.

摘要： By combining a sensing module having a lens and an image sensor with a carriage module having a mirror set, a reading device of a scanning apparatus is assembled. The sensing module further includes two channels at bilateral sides of the lens and two guiding slots disposed on external sides of the channels. The carriage module further includes two linear tracks corresponding to the channels and two bolt hole pedestals corresponding to the guiding slots. The sensing module is glided on the carriage module when the linear tracks are embedded in corresponding channels, thereby correcting the desired magnification.
