摘要:
A method and system for verifying the presence of a lens in a transparent package. The method comprises the steps of moving the package into an inspection position, and conducting a light beam through the package and onto an image plane to form an image of the package on the image plane. The method further comprises the steps of generating a set of signals representing the image on the image plane, and analyzing those signals to determine whether a lens is present in the package. This analyzing step, in turn, includes the steps of searching the package image for images of discrete objects; and for each object image found in the package image, identifying values for a plurality of parameters, and analyzing those identified values according to a predetermined procedure to identify the object as a lens or as not a lens. A lens present signal is generated if one object image found in the package image is identified as a lens; and a lens missing signal is generated if no object images are found in the package image, or if all object images found in the package image are identified as not lenses.

A system and method for inspecting ophthalmic lenses. The system comprises a transport subsystem for moving the lenses into an inspection position, and an illumination subsystem to generate a light beam and to direct the light beam through the lenses. The system further comprises an imaging subsystem to generate a set of signals representing selected portions of the light beam transmitted through the lenses, and a processing subsystem to process those signals according to a predetermined program. The illumination subsystem includes a light source to generate a light beam and a diffuser to form that light beam with a generally uniform intensity across the transverse cross section of the light beam. The illumination subsystem further includes a lens assembly to focus a portion of the light beam onto an image plane, and to focus a portion of the light beam onto a focal point in front of the image plane to form a diffuser background pattern on the image plane.
