Abstract: An apparatus for measuring an absorption coefficient includes a first diffusive material, a second diffusive material inside the first diffusive material separated from the first diffusive material by a cavity, and a transparent material proximate to an inner surface of the second diffusive material that holds an absorptive material. First and second light detectors measure light intensities in the first and second diffusive materials cavity and the transparent material respectively. An absorption coefficient for the absorptive material may be determined based on the first and second light intensities measured when the cavity is illuminated by a light source.

Abstract: An apparatus for optically inspecting an at least partially reflecting surface of an object includes first and second transverse carriers (12, 14) defining respective substantially circular segment-shaped cutouts (32). The transverse carriers (12, 14) are disposed at a longitudinal distance (D) from one another and the longitudinal distance (D) defines a longitudinal direction (17). A plurality of longitudinal members are configured to hold the first and second transverse carriers at the longitudinal distance (D). The longitudinal members are arranged at a defined radial distance to the circular segment-shaped cutouts. A translucent diffusing screen is held in the circular segment-shaped cutouts by the transverse carriers to form a tunnel-shaped inspection space. A multiplicity of light sources are arranged outside of the tunnel-shaped inspection space behind the diffusing screen. The light sources are configured to be controlled individually or in small groups to generate variable light-dark patterns on the diffusing screen. A workpiece receptacle is configured for accommodating the object in the tunnel-shaped inspection space. At least one camera is directed into the tunnel-shaped inspection space. An evaluation and control unit is configured to control the light sources and the camera to generate various light-dark patterns on the diffusing screen and to record and evaluate a plurality of images of the object in dependence on the light-dark patterns.

Abstract: By deriving the image formed by light specularly-reflected from substantially all of the convex (mirror-like) spherical surface of a bearing ball under test that is being illuminated with diffuse light, any defect in the bearing ball under test reveals itself as a light-contrast pattern in the otherwise substantially uniform diffuse background of the image.

Abstract: The invention relates to a device for optically inspecting an at least partially reflecting surface of an item, having a first and at least one second crossbeam (12, 14) each forming a section (32) largely in the shape of a circular segment. The crossbeams (12, 14) are disposed at a longitudinal distance (D) from one another, defining a longitudinal axis (17). The two crossbeams (12, 14) are held at the longitudinal distance (D) by means of a plurality of longitudinal beams (16). The longitudinal beams (16) are disposed at a defined radial distance (38) from the sections (32) in the shape of circular segments. The crossbeams (12, 14) support a light-transparent diffusing screen (34) forming a tunnel-shaped inspection space (36). A plurality of light sources (48) are disposed outside of the tunnel-shaped inspection space (36) behind the diffusing screen, said sources being controllable individually or in small groups in order to generate variable light-dark patterns (90) on the diffusing screen. At least one camera (74, 78) is set up in the tunnel-shaped inspection space (36).
