摘要： An optical alignment system for optimizing a gap distance between an optical fiber end and an optical device uses an atomic force present when the gap distance approaches optimal alignment according to changes in an oscillating fiber amplitude at a fiber resonance frequency. A driving force flexurally vibrates the fiber to produce an oscillation of the fiber at a resonance frequency that produces maximal oscillation. A measurement system detects the amplitude shift at the resonance frequency while adjusting the gap distance.

摘要： An interferometer in which the path length of the reference beam, measured in wavelengths, is continuously changing in sinusoidal fashion and the interference signal created by combining the measurement beam and the reference beam is processed in real time to obtain the physical distance along the measurement beam between the measured surface and a spatial reference frame such as the beam splitter. The processing involves analyzing the Fourier series of the intensity signal at one or more optical detectors in real time and using the time-domain multi-frequency harmonic signals to extract the phase information independently at each pixel position of one or more optical detectors and converting the phase information to distance information.

摘要： An energy collector is used to assist a laser coupling process by reducing the amount of output power of a laser that is used to modify a device attaching element. The energy collector includes an energy collector tip configured to be placed proximate to a device attaching element during the laser coupling process. The energy collector tip is configured to receive laser energy reflected from the device attaching element during the laser coupling process and is formed from a material that converts this reflected energy to heat. Sufficient thermal coupling is created between the energy collector and a surface to provide a conductive pathway for the energy, which has been converted to heat, between the energy collector and the device attaching element.

摘要： An optical package suitable for alignment with a conductively coated optical fiber includes a base having an electrode which forms a capacitance with the conductively coated optical fiber. An optical alignment system computes a capacitance measure when the optical fiber is precisely aligned and further after attachment of the fiber to the package causes a misalignment. The capacitance measures at precise alignment and at misalignment allow computation of a displacement amount from the precise alignment in at least one direction. The optical fiber may be adjusted according to the direction and amount provided by the alignment system to reposition the fiber to its precise alignment.

摘要： A friction drive including a drive shaft that is in rotational motion and in frictional contact with a follower at a contact area. The drive shaft transfers a thrust at the contact area. The follower receives the thrust and provides motion in response to the thrust. A flexure hinge couples the drive shaft to the follower with a constant force while restraining movement of the contact area in the direction of the thrust.

摘要： Optical shutters having a magneto-optical material confined in a holding plate which allows a light to pass through the magneto-optical material. When the intensity of a magnetic field applied to the magneto-optical material is changed, an amount of a polarized light passing through the magneto-optical material is adjusted. A magnetic head with a coil has open ends which are disposed to face the outer surface of a shutter member. A plurality of such optical shutters are arranged to form an optical shutter array.
