    摘要： An optical transmission system (1) alters quantity of incident light by reflecting an optical signal by a micro mirror (11) to enter an optical fiber (13) and by controlling an angle of the micro mirror (11), so that attenuation of the optical signal is controlled. An optical filter (14) is disposed between the micro mirror (11) and the optical fiber (13), for correcting a relationship between a control angle or control voltage of the micro mirror (11) and attenuation of the optical signal to be close to a linear relationship.

    摘要： An optical switch actuator moving an optical element into or out of an optical pathway. The optical element is coupled to a movable shuttle and driven by a motor between two rest positions. The motor includes two stationary coils and a magnet. The shuttle is magnetically latched in the rest positions. The optical element's position at the extended rest position is controlled with a stop that contacts the shuttle to provide accuracy and precision about multiple axes. The material used to construct the actuator's components aids in repeatedly positioning the optical element with precision.

    摘要： The present invention advantageously provides a method and apparatus for the parallel optical processing of a plurality of optical beams within a 2 port optical processing unit. The optical processing unit may perform any of the functions associated with 2 port devices such as: isolators, modulators, filters etc. The present invention further advantageously provides optimal and uniform coupling between each pair of optical fibers, i.e. each discrete pair of access ports, with the optical processing unit. This is achieved in part by a precise geometric arrangement of all elements of the apparatus. The present invention further advantageously provides a reduced form factor and cost when compared with individual 2 port devices.

    摘要： A display system having a greyscale control arrangement for controlling light output from a plurality of optical fibers includes a light source effective for supplying a high brightness light output to the input ends of the plurality of optical fibers. A plurality of piezoelectric shutter members are disposed adjacent the light delivery ends of the optical fibers and are effective for controlling the delivery of light output through the optical fibers as a function of the on or off condition thereof. The delivery ends of the optical fibers are disposed relative to one another so as to form a plurality of display pixels. At least two of the optical fibers are combined to form each of the pixels. The diameters of the at least two optical fibers that make up each pixel are different thereby allowing that at least four different greyscale levels can be achieved for each display pixel.

    摘要： A pupil-replicating lightguide includes an in-coupling grating structure, an out-coupling grating structure, and a phase compensation layer. The out-coupling grating structure has a spatially varying parameter such as grating duty cycle or grating thickness for evening out out-coupled distribution of light. The spatially varying out-coupling grating parameter disturbs the phase of the propagating image light. The phase compensation layer has a spatially varying optical thickness that compensates that disturbed phase to planarize an optical phase profile of out-coupled light, thereby improving a modulation transfer function of the pupil-replicating lightguide.
