摘要： An offset determination system and method permit accurate calculation of an offset of a central feature of an object. The offset determination system and method are particularly suited for, but not limited to, an automatic inspection system for determining the eccentricity of an optical fiber core relative to a theoretical ideal center of an optical fiber termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary. An inspection system 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, the one or more boundary segment images, and the offset determination system and method.

摘要： The injection of a high power beam into an optical fiber is controlled by generating a signal representative of a focus spot on an injection end of the optical fiber (108) and adjusting the optical fiber injection end location dependent upon the representative focus spot signal. Apparatus includes a vision system (116) for generating the representative focus spot signal and a high speed vision processor (124) coupled to the vision system. An x-y-z stage controller (128) is coupled to the vision processor and receives image signals from the vision system. The controller is coupled to a fiber holder (130), and the controller generates control signals which control operation of the fiber holder. The fiber holder includes x-y-z axis stages and means for engaging the optical fiber.

摘要： A first translation stage (13) which holds an optical fiber (11) and a second translation stage (16) which holds a laser diode package (15) are provided, and these translation stages are movable in the X-, Y- and Z-axis directions. A third translation stage (22) movable in the X-, Y- and Z-axis directions is provided, on which are mounted a microscopic video camera (21, 24) and a laser head (33a, 33b). On a video monitor (27) a cursor is moved to the positions of the fiber tip and a laser diode (14) in the laser diode package (15) displayed on the monitor screen and the coordinates of the fiber tip and the laser diode are determined, on the basis of which the fiber tip and the laser diode are moved toward each other. The laser diode is excited and the fiber tip and the laser diode are positioned relative to each other so that the power of laser light received at the fiber tip becomes maximum. Then the laser light is applied from the laser head to the position where to fix the optical fiber, thereby welding or soldering it to the laser diode package.

摘要： In the assembly of a device package, an optoelectronic device (10), such as a light emitting diode (LED) or a photodiode, mounted on a header (14) is aligned with a lens (12), such as a spherical lens, mounted in a housing (2) by making a light beam (23) from a microscope (24) incident on the lens so that light reflected (25) from the lens creates a symmetrical reference image (42, 42', 42"). Light (27) emitted by the device (LED) or reflected from the device (photodiode) forms an object image (44) of the active area of the device. The two images are detected by a camera (28) and are compared (real-image observation by an operator or electronic image comparison by a computer). The device on an x-y table (16) is moved until the object image is centered with respect to the reference image. Then the position of the device within the package is fixed by epoxying, or otherwise securing, the header to the housing (FIG. 1).
