    Abstract: This application relates to an apparatus and method for providing snapshot action thermal infrared imaging within automated process control article inspection applications. More specifically, it pertains to the use of snapshot mode lead salt area-array imaging sensors (20) as the imaging front-end in high-speed machine vision inspection systems (12). the relatively low-cost, good measurement sensitivity at temperatures consistent with thermo-electric cooling means, and the ability to be operated in snapshot mode enables lead salt-based image acquisition sensors (20) to be used in a variety of automated process control and article inspection applications.

    Abstract: This application relates to an apparatus and method for providing patterned illumination fields for use within process control and article inspection applications. More specifically, it pertains to the use of patterned illuminators to enable visual surface inspection of polished objects such as ball bearings. The use of patterned illuminators properly disposed in relation to a polished part under inspection allows small surface imperfections such as scratches and pits to become visible against the normal surface background. The use of carefully engineered illuminators facilitates advantageous defect-site scattering from generally dark field sources. The patterned nature of the illuminators defined by this invention allows the complete surface of three-dimensional parts to be effectively highlighted using dark field illumination fields.

    Abstract: This invention relates to a method and apparatus for mass and/or volume measurements of manufactured articles. More particularly, this invention relates to a method and apparatus for mass and/or volume measurements that can be performed on-line in a part manufacturing process. On-line measurement of the mass or volume of material contained in a specific region of interest of the manufactured items is performed 100% on-line. Real-time process control information is based on real-time measurement of the mass or volume of material contained in a specific region of interest of a manufactured item. Automated quality control inspection for manufactured articles is based on real­time measurement of the mass or volume of material contained in a specific region of interest of manufactured items. A manufacturing closed-loop process is directly corrected to keep it within control limits based on real-time measurement of the mass or volume of material contained in a specific region of interest of manufactured items soon after these items are manufactured.

    Abstract: A solid-state lighting unit for automated visual inspection includes a high-density array of light emitting diodes (12). The packaging density of said diode array being limited only by the physical size of the light emitting diode chips and the ability to perform die and wire bond operations on the bare chips. Each diode is disposed on an electrically insulated, thermally conductive base unit (10). The base unit is, in turn, in a thermally conductive path with a heat dissipator (30). The provisons made to ensure a thermally conductive path from the individual light emitting diode chips to the heat dissipator combined with the high chip packing densities work together to create a solid-state lighting array capable of producing extremely high illumination fields when operated in either pulsed or continuous current mode.
