Abstract: The fiber direction of a carbon fiber material of a test object is detected by means of the polarization direction of light reflected by the test object. If, for example, non-polarized light impinges upon carbon fibers, light reflected by the fibers is polarized in fiber direction.

Abstract: The present invention relates to a color sensor having at least one photosensitive element, in front of which a layer stack of dielectric layers and structured metal layers is constructed, and at least one color filter, through which optical radiation incident on a light input side of the color sensor is filtered before it reaches a photosensitive surface of the photosensitive element. In the suggested color sensor, an array of angle-selective passageways is provided for the optical radiation between the light input side and the photosensitive surface, and each passageway only allows parts of the optical radiation incident on the light input side of the color sensor within a limited angle of incidence range relative to an axis extending perpendicularly to the colour filter to pass through to the photosensitive surface. When the color sensor is manufactured with semiconductor technology, it enables the angle-selective structures to be integrated in the CMOS layer stack. In this way, ultra-flat color sensors can be made.

Abstract: The present invention relates to an optical filter with nanostructured layers and spectral sensors with layers of such kind. The optical filter has at least two nanostructured layers, each of which forms a transmission grating from grating wires extending parallel to each other. The grating wires of the two transmission gratings intersect each other and are positioned one on top of the other in the optical filter. An optical polarise which polarises incident optical radiation linearly parallel to the grating wires of one of the two transmission gratings is arranged over the transmission gratings. The optical filter can be produced as a bandpass filter with standard semiconductor processes without additional layers or modification of said processes.

Abstract: A method for calibrating the colour of a colour monitor with LED backlighting includes at least one area of an image displayed on the colour monitor (1) remotely measured in a spatially resolved manner using a colour sensor (7) configured as an image or line sensor. Deviations of measured colour values from desired colour values are determined in a spatially resolved manner and LED backlighting of the colour monitor (1) is actuated for local correction of the deviations. When the colour sensor (7) is integrated into the remote control (2) of a colour television, the user aims the remote control (2) at the television, and the colour sensor (7) records a test image (3) of the colour television and evaluates it to determine colour corrections. The method makes it possible for the colour of a colour television to be calibrated ex works or in the user's home.
