摘要： At least a representative fraction of the peeled vegetables which have passed through a steam peeler, and abrasive peeler, or both, is presented to a video camera for inspection. The camera output is analyzed by a computer controller to determine the amount of peel remaining on the vegetable and displayed in a visual format to the operator. The controller provides information to the operator on peel fraction remaining so that the operator may manually adjust speed of brush rotation and auger speed or other parameters of the peeling apparatus, or automatically adjusts these parameters to maintain level of peel with varying vegetable attributes. More representative peel fraction data is obtained by analyzing only the central half of the vegetable image captured by the vision system.

摘要： An optical apparatus for providing a two-dimensional output representation of reflection characteristics of an eye fundus in which a laser beam is passed through an anamorphic optical element to produce an output beam focused on a first axis and dispersed on a second axis normal to the first axis forming a line. The line of the output beam is directed onto a scanning element which moves the beam along the first axis and a focusing element directing the output beam from the scanning element through the pupil of the eye onto the fundus, the size of the beam being such that it has a small cross sectional area at the pupillary plane of the eye compared to the diameter of the pupil. The light from the fundus is reflected back through an exit aperture which is large compared to the cross sectional dimension of the input beam at the pupillary plane. The device includes a detector which extends along the non-scanning coordinate of the scanned area. A beam separating means separates the input laser beam from the reflected output beam which is directed toward the detector positioned at a retinal conjugate of the eye. Signal processing means processes the signals received at the detector to provide the two-dimensional output representation.

摘要： A glass defect detection system comprising an apparatus and methods for the real-time inspection for defects in and on transparent sheets, such as a large sheets of glass is disclosed. The defect detection system utilizes a plurality of dark-field illumination systems and bright-field illumination systems and a plurality of baffles. A plurality of imaging devices are deployed to obtain images of transparent sheets. The defect detection system provides uniform lighting capable of equal detection of defects in all orientations and geometries. An image processing system analyzes for defects in and on the transparent sheet.
