摘要： The invention relates to a method and an associated device for determining the transmittance of a flat-glass substrate (40) with a measuring device (10), with which light of at least one light source (20) is guided from one side of the flat-glass substrate (40) through the flat-glass substrate (40) to the opposite side of the flat-glass substrate (40), where it is captured by at least one receiving unit (30) and the transmittance of the flat-glass substrate (40) is determined by means of a comparison between the intensity of the light emitted by the light source (20) and the light incident upon the receiving unit (30). The light source is a surface-like diffuse light source (20), and the receiving unit (30) comprises at least one spatially resolving receiver (31; 31n). By evaluating brightness values in the measuring image (33; 33′) of the spatially resolving receiver (31; 31n), the transmittance is determined in a spatially resolved manner in a partial surface of the flat-glass substrate (40), which is covered by the measuring image (33; 33′).

摘要： An apparatus and a method for measurement of transparent cylindrical articles during their manufacture in high temperature furnaces having openings for viewing the articles as they pass through the furnace. The cylindrical articles may, for example, be optical fiber preforms which have at least two layers of vitreous material and from which optical fibers are made. Measurement is accomplished using a digital camera with a sensing and digital recording device and a lens, and a processor programmed with an algorithm which analyzes the images recorded by the sensing and digital recording device by eliminating noise, identifying and locating the outer edges of the transparent cylindrical article and calculating measurements of the article including the diameter and the axial center of the article.

摘要： A device for inspecting a material with a coated surface includes a light source disposed above the surface that emits light in a wavelength range, at least one first camera for determining a color value of detected light reflected from the surface and an evaluation device. The first camera is disposed above a line located on the surface and configured with a first aperture to detect light from a first point of the line at a first viewing angle and light from a second point separate from the first point at a second viewing angle. The first camera determines a first color value of the first point light and a second color value of the second point light and the evaluation device compares the first and second color values or a color value difference with a predefined color setpoint value or predefined color setpoint value range.

摘要： Non-imaging coherent line scanner systems for measuring at least one defect in a transparent sheet are disclosed. The systems include a laser system that generates coherent diverging laser-line beam, and a cylindrical optical system that forms therefrom a collimated laser-line beam. A movable support member supports and moves the transparent sheet so that the collimated laser-line beam scans the transparent sheet and passes through a portion of the transparent sheet and the at least one defect during scanning. A line-scan sensor system receives the transmitted collimated laser-line beam and a portion of the beam redirected by the defect. The result is an interference image that has at least one coherent defect signature representative of the at least one defect in the transparent object.
