    摘要： A low cost, high reliability system for correcting aberrations in optical signals is disclosed. A foreoptic assembly, such as a telescope, receives an incoming optical signal and directs it to an active optical element, such as a fast steering mirror. The incoming optical signal is diffracted by a diffractive optical element to shape the image that is formed at a wavefront sensor, such as a quad-cell. The wavefront sensor measures a tip-tilt aberration of the incoming optical signal and the active optical element is adjusted to correct the measured aberration. An outgoing optical signal can be transmitted along substantially the same optical path as the incoming optical signal, but in the opposite direction. Thus, the aberration measured from the incoming optical signal can be automatically accounted for in the outgoing optical signal.

    摘要： An apparatus and packaging scheme that ensures that alignments between signal sending and detecting components in transceivers are optimized and maintained over the lifetime of the apparatus. This is accomplished through use of a pair of polymer optical modules, which are used to couple light sent to and received from respective fiber optic cables. During a pre-alignment process, head portions of the polymer optical modules are inserted into respective slots defined in a standoff that is mounted on an optical sub-assembly to which an emitter and detector are mounted, whereby these slots are configured so that the head portions slide along the sidewalls of the slots during assembly. During a subsequent active alignment process, each polymer optical module is positioned relative to its respective emitter or detector until a maximum signal is detected, whereupon the position of the components is quick-set using a UV-sensitive adhesive.

    摘要： A method and apparatus for testing the operability of a signal source formed on a die are described. A pair of modulators are formed on the die and coupled to the signal source. An optical unit is optically coupled to the pair of modulators, which are capable of modulating an optical beam in response to a signal provided by the signal source. The optical unit is capable of detecting modulation of the optical beam. To test the signal source, the signal source is set to generate a signal. If modulation of the optical beam is detected at the optical unit, then the signal source is operable. If modulation of the optical beam is not detected at the optical unit, then the signal source is not operable.

    摘要： A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. Eye reflections from the subjects' eyes are used to steer a high resolution camera to the eyes in order to capture images of the irises. A circular deformable minor driven by one or more annular forces can be used to focus the camera. A circular mirror substrate is mounted by its circumference onto a minor mount and driven by an annular drive element that contacts the minor substrate along a ring. If the annular drive element has a certain diameter relative to the circumference of the mirror substrate, the mirror substrate will be deformed in the shape of a sphere.
