摘要： A method and apparatus for automatically inspecting liquid filled containers for particulate contaminants in relative size. The method comprising the steps of illuminating the liquid with a constant intensity light source, imaging the entire illuminated liquid volume, including the meniscus, into a plurality of image planes with fiber optic bundles, and monitoring the fiber optic bundles with an array of constant sensitivity photo transducers. Each photo transducer continually translates the illumination value of the vial image of an assigned and separate unit volume of the liquid-filled container into a voltage signal and each signal is monitored for a signal change indicative of particulate movement. The interfering output signal due to the meniscus decay is corrected, and the accept/reject decision is based upon a composite signal representative of all the differentiated signals received from the array of photo transducers.

摘要： A method and apparatus for lighting a container which is to be inspected for particulate contamination comprising a first lighting means consisting of two angularly displaced light beams which create an angular shadow zone, a second lighting means of significantly lower intensity than said first lighting means and positioned intermediate the two light beams and a viewing means positioned in the shadow zone.

摘要： A method and apparatus for automatically inspecting liquid filled containers for particulate contaminants in relative size. The method comprising the steps of illuminating the liquid with a constant intensity light source, dissecting the image of the entire illuminated liquid volume, including the meniscus, with fiber optic bundles and monitoring the fiber optic bundles with an array of constant sensitivity photo sensors. Each photo sensor continually translates the illumination value of an assigned and separate cross sectional unit area of the vial image into a voltage signal and monitors each signal for a signal change indicative of particulate movement. The interfering output signal due to the meniscus decay is corrected, and the accept/reject decision is based upon a composite signal representative of all the differentiated signals received from the array of photo sensors.
