    摘要： A ring light illuminator with annularly arranged light sources is disclosed. To each light source there corresponds a beam shaper comprising a light collector, a homogenizing means for light from the light source, and an imaging means for imaging an output of the homogenizing means into an area to be illuminated. The homogenizing means in embodiments is a rod, into which light from the light collector is directed. The end of the rod opposite the light collector is imaged by the imaging means into the area to be illuminated.

    摘要： An impurity measuring device comprises a table (T) on which a sample (S) is placed with its fracture surface (h) upward, an illuminating means (7) for irradiating the fracture surface (h) with light (L) from a plurality of directions, an imaging means (10) for imaging the fracture surface (h) illuminated by the light (L), a dark and light coloring means for subjecting the imaged image to dark and light coloring, and a binarizing means for binarizing the image through comparison between the result of the dark and light coloring and a threshold value. Irradiating the fracture surface (h) with the light (L) from a plurality of directions ensures that the image obtained by imaging the fracture surface (h) is free from shading or optical irregularities due to minute irregularities in the fracture surface (h). Therefore, impurities in the sample (S) from the fracture surface (h) can be accurately detected by subjecting the image to dark and light coloring and binarization.

    摘要： An impurity measuring device includes a table (T) on which a sample (S) is to be placed with its fracture surface (h) facing up, an illuminating means (7) for irradiating the fracture surface (h) with light (L) from a plurality of directions, an image sensing means for sensing an image of the fracture surface (h) irradiated with the light (L), continuous tone color image processing means for processing the sensed image into a continuous tone color image, and a binarizing means for binarizing the continuous tone color image through comparison between the result of the continuous tone color image processing and a threshold value. As the fracture surface (h) is irradiated with the light (L) from the plurality of directions, the image obtained by sensing the image of the fracture surface (h) is free from shading or optical irregularities caused by minute irregularities on the fracture surface (h). Therefore, impurities in the sample (S) can be accurately detected from the fracture surface (h) by subjecting the image to the continuous tone color image processing and binarization.

    摘要： Disclosed are methods and apparatus for imaging a rounded edge of a sample, such as a wafer with a beveled edge. In one embodiment, the system includes a curved diffuser having an internal surface for positioning towards the rounded edge of the sample and an external surface opposite the internal surface and light sources for generating a plurality of illumination beams adjacent to a plurality of positions on the external surface of the diffuser so that the diffuser outputs uniform light onto the rounded edge of the sample at a wide range of incident angles. The system further includes a sensor for receiving light scattered from the rounded edge of the sample in response to the incident light and generating a detected signal for generating an image. These elements are partially or entirely integrated into a compact assembly.

    摘要： Methods and systems detect markings or flaws on the backs of playing cards. The method includes: providing ambient radiation at a gaming table and reflecting some of that radiation off a back surface of a playing card; capturing reflected radiation with a radiation sensor; the radiation sensor transmitting signals based on the reflected radiation captured by the radiation sensor; the transmitted signals providing data that contains image data of the back of the playing card; and displaying an image of the back of the playing card based on the image data. The transmitted signals provide image data of the back of the playing card and are also received by a processor that evaluates or compares that data. The system may be an installed casino system (with eye-in-the-sky technology), a portable box, or a component within a shuffling device or dealer shoe.
