摘要： An optical system suitable for use in machining plastics sheet material using a laser, brings a beam radiant energy in to a line focus on the work piece. The work piece is moving, and the line focus is perpendicular to the direction of such movement. The focused beam is scanned across the work piece in a direction having a component in the direction of motion of the workpiece so that the line focus traverses the work piece in the direction of the line focus. A cylindrical element may be used to form the line focus and a rotating polygonal mirror may perform the scanning.

摘要： A flat disk contains a number of holograms made from the interference of a plane wavefront with spherical wavefront modified by a first cylindrical lens. The disk is rotated so that a plane reconstruction wavefront sweeps across the holograms. The resulting reconstructed wavefront is passed through a second cylindrical lens, resulting in a focussed point sweeping across an object surface in one or more substantially straight lines.

摘要： A method of forming two diverging beams of energy from a single beam of energy including the steps of splitting the single beam of energy into an externally reflected beam and an internally transmitted beam at a first surface on a wedge shaped energy beam splitting device; splitting the internally transmitted beam into an internally reflected beam and an externally transmitted beam at a second surface of the wedge shaped energy beam splitting device, and substantially totally reflecting the internally reflected beam between the first and second surfaces until the internally reflected beam reaches an end of the wedge shaped energy beam splitting device. The above method may further include steps paralleling the above steps wherein two diverging beams of energy are formed from a second beam of energy impinging on the second surface and then combining the two diverging beams with the two diverging beams formed from the beam of energy split by the first surface, to form first and second combined beams. The preferred apparatus for performing the method is an energy beam splitting device having a first surface for splitting an incident beam energy into an externally reflected beam and an internally transmitted beams, a second surface spaced from the first surface for splitting the internally transmitted beam into an externally transmitted beam and into an internally reflected beam, and the second surface intersecting the first surface at an angle that impinges the internally transmitted beam on the second surface at an angle of incidence that is less than the minimum angle necessary for substantially total internal reflection and impinges said internally reflected beam on the first surface at an angle of incidence that exceeds the minimum angle necessary for substantially total internal reflection. The above device may further be used as a beam combiner by having the second surface split a second incident beam of energy into two diverging beams of energy and combining the two beams produced by the first surface with the two beams produced by the second surface to form first and second combined beams.

摘要： A two-dimensional light deflector is shown which comprises a cylindrical member having a plurality of holograms recorded thereon. A collimated light beam is directed to illuminate the hologram cylinder and rotation of the hologram cylinder provides a line scan which is at an angle of about 45.degree. with respect to the plane of rotation of the cylinder. The azimuthal position of the line scan can be varied by the rotation of a small mirror which directs the illumination beam. As a consequence, a two-dimensional raster scan on a cylindrical image surface is produced.

摘要： An optical system for a scanning apparatus uses a folded optical path with certain mirrors moving, the movement of the mirrors such that the length of the optical path, and thus the magnification, is maintained constant. Either a fixed or movable lens system can be provided. With a fixed lens system there is differential movement of mirrors. With a moving lens system, the lens system and image receiver move in fixed relationship with the scanning mirror.

摘要： This patent discloses an improved inspection tool for rapidly inspecting miniature electronic conductor patterns, circuits and the like. The tool focuses a laser beam to a small laser spot that raster scans a large conductor pattern area on the workpiece being inspected. Reflected laser light from the workpiece impinges upon a light detector that generates electrical signals according to the presence or absence of conductor pattern material on the workpiece at the momentary X and Y coordinate of the scanning laser spot. The light detector signals are compared with a previously encoded data image of the correct circuit pattern for the X and Y coordinates of the scanning laser spot. When the signals and the data agree at all X and Y coordinate points the workpiece is accepted. If the signals and the data do not agree at one or more X and Y coordinate points a defect in the circuit pattern is indicated. A defect may indicate out-of-tolerance dimensions, possible electrical short circuits, and/or open circuits. The extent of a defect may be determined by adjacent X and Y coordinate points and suitable computer programming, while workpieces having extended or out-of-tolerance defects are rejected. The improved disclosed inspection tool includes apparatus for automatically compensating for variations in the workpieces, and to effect registration for the scanning laser spot.

摘要： Apparatus for use in a radiation scanning system comprising a radiation detector and an optical system arranged to scan radiation from a field of view across the radiation detector. The optical system includes two sets of planar reflective surfaces, one set being movable relative to the other, and a rotary assembly carrying one of the sets and rotatable about an axis of rotation. The detector is arranged relative to the optical system such that the radiation enters the detector after sequential reflection from reflective surfaces of the two sets, and the surfaces which effect the sequential reflection being separated by a predetermined amount and being located with respect to the axis of rotation such that the angle of incidence of radiation at the detector is independent of the position of the radiation in the field of view.

摘要： A laser scanner is disclosed which is especially adapted as a label reader for point-of-sale data processingsystems. The scanner produces a polyphase scan pattern. The scanning beam is vertically deflected as a sinuosoidal function of time by an oscillatory mirror and is horizontally deflected as a sawtooth function of time by a rotary multifaceted mirror. The return light signal follows an optical path including the rotary multifaceted mirror which causes "derotation" of the image before it impinges upon the receiving photodetector. Additionally, the ambient or background light is reduced by providing an optical slit in the receiving optics so that the vertical deflection is accommodated.
