摘要： An automatic inspection method contactlessly measures the offset of a feature of an object from a theoretical ideal center of the object, and is particularly suited for measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of the termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary. An inspection system for implementing the novel inspection method has a feature imager, one or more boundary segment imagers but preferably four in number, and a machine vision system connected to the foregoing imagers. The feature imager is positioned to capture an image of the feature (e.g., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object (e.g., termination endface). The machine vision system determines the offset, or eccentricity, based upon the feature image and the one or more boundary segment images.

摘要： A balanced focus system and method achieve optimal focus of different areas of an object that are concurrently imaged and then combined to form a combined image. The balanced focus method is particularly suited for, but not limited to, use with an automatic inspection system for contactlessly measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of an alignment surface of the termination. The inspection system has an imaging system with a feature imager and one or more boundary segment imagers but preferably four in number, a focus adjustment mechanism (FAM) for adjusting the position of the imagers relative to the imaged object along an optical axis, and a machine vision system for receiving image data from the foregoing imagers and configured to control the FAM. The feature imager is positioned to capture an image of the feature (e.g., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object (e.g., termination endface). The machine vision system determines the eccentricity based upon the feature image and the one or more boundary segment images. Significantly, the machine vision system employs the balanced focus system and method to achieve an optimal focus position for the imaging system based upon a series of combined images and a statistic S that is computed for each of the sampling locations.

摘要： The present invention is an optical monitoring and test access interconnection module especially adapted for use with a fiber optic distribution frame for a fiber optic communications system. The interconnection module provides a combination of monitoring and test access for two fiber lines, typically a transmit/receive pair, where wavelength division multiplexer (WDM) test access is provided to both the transmit and receive fibers. In one embodiment of the present invention, the interconnection module monitors only the receive fiber line where a power monitoring circuit receives a monitor level optical signal via an optical tap and converts the optical signal to an electrical output. Processing electronics and firmware within the module are operable to generate alarms and other control signals when changes in the power level of the received signal are detected. A test access path is provided on the module for use, for example, with an optical time domain reflectometer (OTDR). In one embodiment of the present invention, the interconnection module incorporates a unique physical design arrangement that separates the optical signal processing from the electronic processing into partitioned sub-modules. The optical and electronic sub-modules may advantageously be assembled (and dis-assembled) by means of guides that allow the module halves to slide together. A unique optical mating connector is provided in the sliding arrangement to join the optical module to an opto-electronic photodetector in the electronic module.
