    摘要： A laser beam pointing and positioning system includes first and second rotatable diffraction gratings. Each grating deviates a laser beam by a predetermined angle of deviation. The relative rotational position of the gratings is controlled to change the beam steering angle and direction of a laser beam. A maximum beam steering angle of twice the angle of deviation may be achieved in any direction. The diffraction gratings may be etched on transmissive substrates of optical glass, sapphire, silicon (Si), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS), or Germanium (Ge). The substrates may be positioned within rotary elements coupled respectively to electromechanical positional control elements to rotate the gratings.

    摘要： A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel (100) is used to read bar codes on packages (101, 102, 109-116) entering the tunnel, while a package dimension subsystem (3500) is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identification data (3502) is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

    摘要： An optical beam scanning apparatus of a high resolution, compensates the increase and change of the diameter of a scanning beam, uneven rotation of a hologram rotating body, the positional changes in the directions of main and subscannings by the mode hopping of the wavelength of a semi-conductor laser, and the deterioration of the parallelism of the base of the hologram rotating body, etc., which mar the resolution and impede the cost reduction of a hologram scanner. The apparatus uses only the holograms that are duplicated in large quantities, without using auxiliary optical systems such as optical lenses and mirrors with curvatures. On a rotating body (1) and a fixed plate (2), provided are respectively diffraction gratings (1a, 2a) which minimize the sum of the weighted values of the squared or absolute values of the differences of two light path lengths, the weighting being conducted for each of scanning points on the entire image-forming surface (4). One of the two optical path length is of a light beam on the principal axis (MA), which is diffracted by the diffraction grating (1a) and by the diffraction grating (2a) and then, is focused at a scanning point (k) on the image-forming surface (4); the other is of a light beam on a peripheral axis (MI) different from the principal axis (MA). Alternatively, the diffraction gratings (1a, 2a) minimize the sum of the weighted values of the squared or absolute value of the sum of two phase differences, the weighting being conducted for each of scanning points on the entire image-forming surface (4). One of the two phase differences is the shift of the phase of the diffraction grating (1a) on the rotating body (1) from the principle axis (MA) when the light beam is focused at the scanning point (k); the other is the shift of the phase recorded on the diffraction grating (2a) from the principle axis (MA) when the light beam strikes the stationary plate (2).

    摘要： A method for making an image line (10) with a laser beam, according to which the laser beam is created by a laser (1); the intensity of the laser beam is modulated by an external modulator or by said laser (1); said modulated laser beam is fed into a coding element (2, 3), by means of which at least one of the properties of the laser beam is transformed, e.g. amplitude, phase or direction, using an electrical control signal; the coded laser beam is fed into the hologram (9), by means of which the laser beam is transformed into focused image spots (20...24 a, b, c); from said image spots (20...24 a, b, c) an image line (10) is formed on the image plane and said laser beam is guided and transformed by optical elements. According to the invention by means of said coding element (2, 3) the above mentioned characteristic of said laser beam is changed so that when changing the input signal to said coding element (2, 3) a number of coded, in some sense orthogonal fields are created; said optics and said holograms (9) are designed together with the coding element so that with the aid of said hologram (9) the coded fields are separable so that each separate field forms one said image spot (20...24 a, b, c) on said image plane; scanning the input signal of said coding element (2, 3) across its values, a number of said image spots can be formed (20...24 a, b, c), which form said image line (10) and said coding element (2, 3), said optics and said hologram (9) are so designed that the position error of said image spots (20... 24 a, b, c) can be diminished by means of electronic circuits.
