摘要： A head for directing radiated energy from a source to a coordinate in a field of view defined by at least one of azimuth and elevation, comprises an angled element and a planar reflecting element. The angled element rotates about a first axis and redirects the beam, the redirection of the angled element differing in at least one of direction and extent as it is rotated. An axis normal to the surface extends at an angle to the second axis. The reflecting surface receives the redirected beam at a point thereon and reflects it in a direction within the FOV. A rotator may be positioned between the source and the angled element to support and independently rotate the angled element and the reflecting surface about the first and second axes without impeding the energy.

摘要： An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, an EIR device including a two-dimensional imager, and a micro-projector including a light source and a light manipulation sub-system. The EIR device can be configured to output raw message data containing an encoded message and/or output a decoded message corresponding to an encoded message. The EIR terminal can be configured to acquire an image of a target object in a field of view (FOV) of the two-dimensional imager. The EIR terminal can be further configured, responsive to successfully locating decodable indicia within the image, to produce a decoded message by decoding the decodable indicia. The EIR terminal can be further configured, responsive to successfully decoding the decodable indicia, to generate a projectable image and to project the projectable image onto a surface the target object using the micro-projector.

摘要： A beam steering device includes a housing and a transceiver that emits and receives light beams through at least one opening in the housing. A rotator includes a cylindrical body rotatably mounted within the housing axially between the transceiver and the at least one opening. A wedge-shaped prism is secured within the body and includes a first surface extending perpendicular to the axis and a second surface extending transverse to the axis. An encoder member and a drive member are provided on an outer surface of the body. Sensors are mounted to the housing to sense the encoder member and provide an encoder signal indicative of a rotational position of the prism about the axis. At least one drive element is mounted to the housing and applies force to the drive member to rotate the body and prism about the axis for steering light beams propagating through the prism.

摘要： A beam brush includes one lens fixed for receiving a laser beam propagating along a first beam axis, a retroreflector positioned for redirecting the laser beam onto a second beam axis through a change in beam path length, and a second lens transmitting the redirected beam. The retroreflector is rotatable about an offset axis and has its angle of rotation controlled for affecting a change in beam path length. The angle of rotation resulting in the path length change is selected for providing a focus or divergence of the reflected beam transmitted through the second lens. Such a system is useful as a Z-axis focusing device operable an X-Y scanner located downstream the modified beam.

摘要： A system and method for scanning a wide band beam is presented. An apparatus includes a pair of prism triplets. Each prism triplet includes a first wedge prism, a second wedge prism and a third wedge prism all formed with different optical materials. In operation, a beam passing through the wide band team scanning apparatus first passes through the first, second and third wedge prisms of the first prism triplet. The beam then passes through the wedge prisms of the second prism triplet in a mirrored order (the third, then second, then first wedge prisms) than that of the first prism triplet. This apparatus with two prism triplets allows wide band light transmitted through it to emerge with its plurality of different wavelengths of light travelling in the same direction to equalize net dispersive effects each of different wavelengths.
