摘要： A webcam apparatus, having a display surface characterized by a display area, includes an image capture device characterized by an optical axis and a first footprint in a plane perpendicular to the optical axis; and an energy transfer device with a first portion coupled to the image capture device; and a second portion allowing attachment to an edge of a display screen. When attached, the image capture device and the first portion lie against and in contact with the display surface, or in a proximate and parallel plane. An optical axis characterizing the image capture device is aligned with a gaze direction of a user addressing a viewer via the captured images. The first portion of the energy transfer device is transparent at optical wavelengths, and has a second footprint in the plane perpendicular to the optical axis. The first and second footprints are small relative to the display area.

摘要： Test instruments constituting an automatic test system are characterized in terms of execution time data. The execution time data is composed of a set of execution times. Each of the execution times is the time required for the test instrument to perform a respective testing operation. The test instruments additionally have the ability to communicate their respective execution time data to such recipients as others of the test instruments, the system controller and recipients outside the automatic test system. Additionally, such test instruments have the ability to communicate test results to at least one other of the test instruments and the ability to process test results received from at least one other of the test instruments. Such characterization, communication and processing allows a system integrator to devise execution time-dependent test programs as part of a test suite that allows test throughput to be maximized.

摘要： An optical position-tracking system comprises a first light beam steering device for sweeping a first light beam through a first angular range to cause a reflection of the first light beam by a target. Additionally, the optical position-tracking system further comprises a second light beam steering device for sweeping a second light beam through a second angular range to cause a reflection of the second light beam by the target. Moreover, the optical position-tracking system enables determination of a position of the target using a triangulation technique utilizing a first angular value of the first light beam and a second angular value of the second light beam. The first angular value and the second angular value depend on the existence of the respective reflection.

摘要： A system for characterizing optical properties of a device under test (DUT) uses an expanded local oscillator signal to perform multiple parallel interferometric measurements. In one system, the expanded local oscillator signal is optically connected to a lens array. The lens array focuses the expanded swept local oscillator signal into multiple beams. The multiple beams are then used in multiple parallel interferometric measurements. The multiple beams may be used as the reference beams or applied to the DUT and used as the test beams depending on the application. The test beams and reference beams are combined to perform the interferometric measurements. In another system, a portion of the expanded local oscillator signal is applied directly to a DUT as the test beam while another portion of the expanded local oscillator signal is used for the reference beam.

摘要： A heterodyne optical network analyzer and method for device characterization reduces the effect of relative intensity noise (RIN) in interferometric optical measurements by subtracting the measured intensities of first and second interference signals derived from an optical interferometer. The first and second interference signals are produced by combining a first lightwave transmitted to an optical device being characterized with a second lightwave, which is a delayed version of the first lightwave. The first and second lightwaves are derived by splitting an input lightwave having a continuously swept optical frequency generated by a light source, such as a continuously tunable laser.

摘要： A tunable optical filter utilizes multiple electroholographic (EH) gratings with different center wavelengths to filter an optical signal over a wide wavelength range. The EH gratings are connected such that an input optical signal passes through at least one of the EH gratings. The EH gratings are activated and tuned by electrode pairs that are controlled through a voltage controller. The tunable optical filter is coarse tuned by activating the EH gratings having a wavelength range that includes the center wavelength that is to be filtered and fine tuned by adjusting the voltage that is applied across the activated EH gratings.

摘要： An optical heterodyne detection system includes an input signal and a local oscillator signal that are combined in an optical coupler and output as a first beam and a second beam. A polarizing beam splitter is optically connected to the optical coupler in order to receive the first beam and the second beam. The polarizing beam splitter includes four outputs for outputting four beams to four photodetectors including two polarized portions of the first beam and two polarized portions of the second beam. The four photodetectors generate four electrical signals in response to respective ones of the four beams. The four electrical signals are transmitted to a processor and processed to provide an output response that is independent of the polarization state of the original input signal and in which the intensity noise has been suppressed. Processing of the electrical signals to suppress the intensity noise involves canceling the intensity noise component of similarly polarized beams by subtracting the similarly polarized beams. Processing of the electrical signals to provide polarization independence involves squaring the values generated from the two subtraction operations, low pass filtering the values generated from the two squaring operations, and then adding the values generated from the two filtering operations.

摘要： A tunable optical cavity constructed from a fixed mirror and a movable mirror is disclosed. A circuit applies an electrical potential between first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror and the moveable mirror are positioned such that the mirrors form the opposite ends of the optical cavity. The distance between the fixed mirror and the moveable mirror is a function of the applied electrical potential. The thermally induced vibrations are reduced by utilizing an electrical feedback circuit that measures the distance between the mirrors. The feedback circuit dynamically changes the potential between the substrate and the support member so as to reduce fluctuations in the cavity resonance frequency.
