    摘要： A scan module in a reader for, and a method of, electro-optically reading symbols, include a light source for directing light at a symbol during reading, a light detector for detecting return light from the symbol during reading and for generating an electrical signal indicative of the detected return light, and an object sensor for sensing an object bearing the symbol and for generating a trigger signal for initiating the reading. The light source, the light detector and the object sensor are all supported by a common chassis.

    摘要： A plurality of solid-state imagers is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing images along different fields of view of diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. The imagers are commonly mounted on a circuit board for joint installation at, and joint removal from, the reader for ease of serviceability.

    摘要： A solid-state imager is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing light along an optical axis over a field of view from diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. An optical converter is located within the housing, for optically modifying and asymmetrically magnifying the field of view along mutually orthogonal directions generally perpendicular to the optical axis, and for increasing resolution of the imager along one of these directions.

    摘要： An imaging based bar code reader for imaging and decoding a target bar code. The reader features a housing including a scanning head defining a horizontal axis and an imaging system supported by the housing for imaging the target bar code. The imaging system including a 2D sensor array and focusing optics receiving reflected illumination from the target bar code through the window and focusing the reflected illumination onto the sensor array. The sensor array includes an orthogonal array of pixels and defines a horizontal axis. The reader further features a decoding system for decoding an image of the target bar code. The sensor array is oriented such that the horizontal axis of the sensor array is at an acute angle with respect to the horizontal axis of the target bar code when the target bar code is being presented to the scanning head such that the horizontal axis of the target bar code is substantially parallel to the horizontal axis of the scanning head.

    摘要： A substantially uniform distributed illumination pattern of light is generated on and along a symbol to be read by image capture. A solid-state imager is mounted on a tilted printed circuit board in a tilted handle of an ergonomic reader. An imaging lens assembly captures return light over a field of view from the symbol along an imaging axis, and projects the captured return light onto the imager. An illumination light source is mounted on the board for emitting illumination light at an acute angle of inclination relative to the imaging axis. An optical component includes a first lens portion with a polynomial incident surface for intercepting, bending and aligning the emitted illumination light to generate the pattern in a scan direction along the symbol, and a second lens portion with a toroidal or cylindrical aspherical surface for collimating the aligned illumination light to generate the pattern in a transverse direction.

    摘要： A bioptical workstation includes plural image capture modules for capturing images of indicia along different fields of view. Each module includes an illuminator for illuminating the indicia with illumination light, a megapixel imager with a rolling shutter for sequentially capturing the return light, and a shutter element for passing the return light to its imager in an open state, and for blocking the return light from other modules from reaching its imager in an closed state. A controller prevents interference among the modules by controlling the shutter element to assume the open state only during a respective exposure time period during which its imager produces an electrical signal indicative of the indicia, and by controlling the shutter element to assume the closed state at all times other than the respective exposure time period to prevent capture of the return light from the other modules.
