摘要： This disclosure concerns methods for transmitting a signal in an optical system. In one example, the method begins when an optical signal is generated. Then, the optical signal is manipulated such that the optical signal defines a substantially annular intensity profile, where power of the optical signal varies in the intensity profile. Finally, the optical signal is launched into an input face of an optical fiber such that a predetermined part of the intensity profile of the optical signal is located proximate an optical axis associated with the optical fiber.

摘要： A zero-clearance receptacle for single mode optical fiber couplers. The zero-clearance receptacle includes an internally fluted V-groove formed by internally extending legs. The zero-clearance receptacle uses the fundamental action of the V-groove to accurately locate an optical fiber ferrule inserted into the zero-clearance receptacle in the radial direction. The zero-clearance receptacle further includes a slot that receives a biasing element, such as a spring, that biases the optical ferrule against the V-groove legs. This enables accurate positioning of an optical fiber in the optical ferrule relation to an optical element such as a VCSEL or a photoreceptor. The zero-clearance receptacle beneficially fits into an optical coupler, which may have a lens.

摘要： Systems and methods analyze the performance of a mechanical system having two identical rotating members therein. Light is directed from two identical light sources to intercept encoded portions of the rotating members. A portion of the light is reflected from the encoded portions of each rotating member. The reflected portion of the light can be then detected to recover performance data maintained therein, wherein the performance data contains performance characteristics of the mechanical system. A reflected portion of the light can be detected to recover performance data. The light sources can be configured as Vertical Cavity Surface Emitting Lasers (VCSEL). The encoded portions of rotating members thereof can include a bar code. Images from a first encoded surface may interact with an image from a second encoded surface after the light beams are reflected off the first and second rotating surfaces to produce Moirè fringes.

摘要： A method and apparatus for sensing a presence of a magnetic field and/or a magnitude of a magnetic flux density of the magnetic field. A direct-current voltage is applied across a first layer of a conductive material, so that a direct current flows in a first direction through the first layer. A second layer of a piezoelectric material is integrated with or positioned adjacent or abutting the first layer. The first layer and the second layer are exposed to or positioned within a magnetic field. A Lorentz force is thus caused, preferably in a direction which is generally perpendicular to the first direction of the direct current and a second direction of the magnetic field to deflect the piezoelectric material thereby causing an output voltage in response to the Lorentz force. A magnetic flux density can be calculated as a function of the piezoelectric output.

摘要： A sensor for optically detecting a location of an object within a field of the sensor includes first, second and third photodetectors arranged to receive photons from respective first, second and third sensing zones within the field of the sensor. The first, second and third sensing zones are adjacent to one another and the sensor includes a processing circuit that receives first, second and third signals from the respective first, second and third photodetectors. One of the first, second and third signals is indicative of photons reflected by the object within the field of the sensor and the processing circuit compares the one of the first, second and third signals to another one of the first, second and third signals and a predetermined threshold value to determine the location of the object within the field of the sensor.
