Abstract:
A fiber optic inspection system for use in the inspection of sandwiched solder bonds in integrated circuit packages. The apparatus contains a miniature fiber optic probe which picks up an image of the solder bonds and transmits it to a video camera. The video output signal of the camera is image processed to enhance the picture quality and displayed on a video monitor.
Abstract:
A system for the automatic observation and quantification of phenomena capable of being detected by fluorescence and appearing in a localized zone (8), the system comprising a source of radiation (2), optionally associated with an excitation filter (5) to send on the localized zone (8) an excitation radiation capable of producing the fluorescence, optical observation means (7) of the localized zone (8) and at least one filter (12) intended to block the excitation radiation and arranged in the path of the luminous radiation of fluorescence emanating from the localized zone (8). In accordance with the invention, the localized zone (8) is observed by a picture-taking tube (17) and through colored filters or windows on a disc (18) intercepting beam 11. The sucessive colored images are memorized and then read simultaneously.

The invention also relates to a device for executing such a process and a line comprising such a device.
Abstract:
A method, system and computer-readable storage medium are provided to facilitate inspection of a composite part during manufacture. In the context of a system, a system for inspecting a composite part during manufacture is provided that includes an inspection system configured to detect an in-process anomaly with respect to a ply of the composite part during placement of the ply. The system also includes a computing system configured to determine part location coordinates of the in-process anomaly detected by the inspection system with respect to the ply of the composite part. The computing system is also configured to map the in-process anomaly to a digital part model based upon the part location coordinates. The system additionally includes a display, responsive to the computing system, configured to present a representation of the digital part model including an indication of the in-process anomaly relative thereto.
Abstract:
A method and device for automatically identifying a point of interest (e.g., the deepest or highest point) on the surface of an anomaly on a viewed object using a video inspection device is disclosed. The video inspection device obtains and displays an image of the surface of the viewed object. A reference surface is determined along with a region of interest that includes a plurality of points on the surface of the anomaly. The video inspection device determines a depth or height for each of the plurality of points on the surface of the anomaly in the region of interest. The point on the surface of the anomaly (e.g., having the greatest depth or height) is identified as the point of interest. A profile of the object surface at the point of interest is then determined.
Abstract:
A system for classifying different types of sheeting materials of road signs depicted in a videostream compares estimated retroreflectivity values against known minimum retroreflectivity values for each of a plurality of colors. Once a road sign has been identified in the videostream, the frames associated with that road sign are analyzed to determine each of a plurality of colors present on the road sign. An estimated retroreflectivity for each of the plurality of colors present on the road sign is then determined. By comparing the estimated retroreflectivity for each of the plurality of colors against known minimum retroreflectivity values for the corresponding color for different types of sheeting materials, an accurate determination of the classification of the sheeting material of the road sign is established. Preferably, certain conditions of gross failure of the sheeting material are filtered out before classification of the sheeting material is determined.
Abstract:
A system, suitable for high-speed operation, by which raw product (45), such as a slab of meat, can be accurately processed, such as by slicing into segments of desired weight, comprises a product profiling apparatus (15). The product profiling apparatus (15) measures the profile of the physical process. The product profiling apparatus (15) includes line lasers (75, 85) for directing a line of light across the upper and lower surfaces of the product (45) and visual image cameras (80, 90) directed toward the profile surface to capture, at fixed increments, the product profile. The product may also be weighed and the product density determined from the overall profile measurements. A controller (150) receives this data, and instructs the physical process accordingly.

Abstract:
A method and apparatus for checking the surface state of one face (2) of a solid (1) in order to locate shape defects which may be present therein. The observation of the face to be checked takes place by means of photography using a large field video camera (3) and a small field video camera (4). The size of the located defects is measured by an optoelectronic sensor or probe (11). The apparatus can be controlled by an operator or can have automatic control.
Abstract:
A workpiece surface is measured to detect a defective portion with a projection and a depression on the workpiece surface by using an optical inspecting apparatus having a projector for radiating a detecting light towards the workpiece surface and a picturing device for receiving a reflected light from the workpiece surface. A reflected light from the workpiece surface is pictured in a condition in which a focal surface of the picturing device is positioned away from the workpiece surface to the side of the picturing device relative to an entire region of that effective inspecting range of the workpiece surface from which the picturing device can receive the reflected light. The defective portion on the workpiece surface is detected from a dark portion which appears on the image of the picturing device.
