20080212154 | MOTION COMPENSATED LIGHT-EMITTING APPARATUS - A light-emitting apparatus, for enabling a beam of light to be projected on a desired target located a distance away to project the beam on the desired target without any or substantially any undesired movement. The apparatus may include a housing, a light generating device located within the housing and operable to generate a beam of light, a sensing device or devices for sensing an undesired action of the housing, a control circuit operable to provide a control signal corresponding to the sensed undesired action, and a drive device operable to counter act all or at least some of the undesired action of said housing in accordance with said control signal. The sensing device or devices may be one or more gyroscopes, accelerometers or other such devices. | 09-04-2008 |

20080259422 | SELECTIVE PHOTOCOAGULATION - A method of scanning a laser beam across a set of cells includes during a first interval, scanning a laser beam across a set of cells; and during a second interval, deflecting the laser beam away from the set of cells. The first interval is selected to cause microcavitation in at least a portion of the cells from the set of cells. | 10-23-2008 |
20080304123 | TWO DIMENSIONAL OPTICAL SCANNING IMAGE SYSTEM - An ultra high speed miniature two dimensional electro-optic image acquisition system uses prisms of varying geometries to control the amount of horizontal deflection and a Bragg grating to control the amount of vertical deflection. A collimating lens array and a Gaussian profile Bragg grating help confine the beam diameter of the deflected light beam. A separate prism further bends light into the vertical direction. A spherical lens focuses light onto a photodetector array for display. | 12-11-2008 |
20090021816 | APPARATUS AND METHOD FOR LASER AND OPTICAL COUPLING - An apparatus and method steer a light through a lens into a receiving port via a steering device. The steering device is located between the lens and a light source. A feedback mechanism adjusts the steering device to correct for aberration. | 01-22-2009 |
20090046338 | Beam Positioning and Pointing - A beam pointing and positioning system includes a first lens, movable in a first plane perpendicular to a nominal optical axis, which receives and positions a light beam. The system also includes a second lens, movable in a second plane perpendicular to the nominal optical axis, which receives and points the positioned light beam. The system is thereby capable of directing the light beam to a desired location at a desired angle. The system may also include a beam splitter that receives, transmits, and reflects the pointed light beam, one or more sensors that receive the reflected light beam, and a controller coupled to the sensor(s) and first and second lenses. The controller may control the positioning of the first and second lenses based on beam position and pointing data and/or signals received from the sensor(s). A method of positioning and pointing a light beam is also presented. | 02-19-2009 |
20090046339 | OPTICAL LENS MODULE - An optical lens module including a foundation, at least one actuator, a lens base, an optical lens, at least one shaft, and at least one rocker arm is provided. The actuator is disposed in an accommodation space, defined inside the foundation, and fixed on the foundation. The lens base is disposed in the accommodation space and beside the actuator. The optical lens is disposed on the lens base. The shaft has a first end and a second end opposite to the first end. The first end is solidly connected to the lens base. The second end is connected to the foundation. The rocker arm has a third end and a fourth end opposite to the third end. The third end is solidly connected to a portion of the shaft between the first end and the second end. The fourth end is connected to the actuator. | 02-19-2009 |
20090046340 | LIGHT STEERING USING AN ARRAY OF TUNABLE PHASE DELAY ELEMENTS - An apparatus and method for steering a beam of light using an array of tunable optical phase delay elements is presented. The sidelobes of an angular spectrum of light reflected from the array are causing an optical crosstalk. The selected sidelobes are suppressed by perturbing the phase delay pattern of the array elements. The pattern of perturbations is found by linearizing a system of equations describing dependence of the angular spectrum of the reflected light on the phase delays introduced into the wavefront of light by the elements of the array. | 02-19-2009 |

20090073523 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS - In an optical scanning device, a light-source driving unit drives a light source to modulate a light beam in units of single dot, a deflecting unit deflects the light beam, and a scanning optical system guides the deflected light beam to a scanning surface having an active writing area for forming an image. A static beam spot size, which is a beam spot size of the light beam on the scanning surface when the light beam passes a predetermined image height, is set such that a scanning beam spot size, which is a beam spot size of the light beam on the scanning surface when the light beam is moved to scan during the light beam exposes a single dot, is kept substantially constant. | 03-19-2009 |
