摘要： Optical scanning of one- and two-dimensional barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user and thereafter using a second, larger and more robust scan pattern for decoding. During aiming, the symbol is partially decoded to determine type and orientation, and this information is applied to control the angle of the scan pattern produced, the rate at which the scan pattern is increased for optimum decoding, and the ultimate pattern size. Preferred scan patterns, as well as unique scan mechanisms, are described.

摘要： A hand-held optical reader for reading printed indicia on a remote target includes a light source for generating a scanning light beam and a detector for detecting the light reflected from the printed indicia. The light source and detector are housed within a housing having a window through which the light beam passes from the source to the target for reflection from the target to the detector. The housing includes parallel front and rear faces, each being generally rectangular in shape and having a lower portion and upper portion. The front and rear faces are joined by a substantially planar base face at their lower edges. The window is disposed in the front face with the reader being ergonomically configured so as be comfortably held in the hand of a user, with the user's palm adjacent the rear face to enable the user to direct the scanning light beam at a remote target.

摘要： Optical scanning is established by superimposing the alternating magnetic field of a coil magnet with the permanent field set up by a permanent magnet which surrounds the coil magnet. Both magnets are fixedly secured to a support at one axial end of the magnets and a flexible diaphragm is secured to the other axial end of the permanent magnet. A scanning mirror is effectively attached between the support and the diaphragm. When the coil magnet is activated, the diaphragm is rapidly flexed which causes the movement of the scanning mirror.

摘要： A reader for electro-optical reading bar code symbols of reduced height, comprises a light source for generating a light beam along an optical path; a pair of oscillatable reflectors in the optical path; a first drive for oscillating the reflectors at different frequencies that are a ratio of about 10%-30% apart to create a scan pattern; and a second drive for rotating the scan pattern about an axis that is generally orthogonal to the scan pattern.

摘要： An integrated optical module for an optical scanner has a lens spaced from a vertical-cavity surface-emitting laser (VCSEL) by a spacer of defined dimensions. The module, in an alternative embodiment, includes a wafer frame, a suspended mirror mounted for oscillation on the frame, a wafer substrate bonded beneath the frame and a wafer cover bonded above the frame. The cover includes a mirror travel stop to protect the mirror against shocks. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element onto the oscillating mirror. The reflected beam passes out of the module toward an indicia to be read. Large numbers of such devices may be fabricated relatively cheaply using wafer-scale processing and assembly technology. Three large wafers are fabricated corresponding respectively to arrays of substrates, frames and covers. The large wafers are bonded together in a sandwich arrangement, and are then diced to produce the individual scan modules. The modules may provide either one-dimensional or two-dimensional scanning.

摘要： An optical scanner such as a bar code scanner includes a laser diode to create the scanning laser beam. Laser diodes are characteristically astigmatic, and when passed through a rotationally symmetric lens the beam typically forms a waist both in the x (scanning) direction and in the y (perpendicular) direction. The width of the beam envelope in the x direction is adjusted by means of a conventional lens. The width of the beam envelope in the y direction is adjusted by the use of a non-planar mirror, preferably a cylindrical mirror, as the rotating or oscillating element.
