摘要： The present invention relates to an encoding device, such as an optical position encoder, for encoding input from an object, and a method for encoding input from an object, for determining a position of an object that interferes with light of the device. The encoding device comprises a light source, a waveguide, a number of redirecting structures, and a detector. By means of the waveguide and the number of redirecting structures, light from the light source is guided towards the detector along a path that includes traversing an area in a space next to the planar waveguide. An object may be positioned in the area in the space and may interfere with the light, which interference may be encoded into a position or activation.

摘要： The present invention relates to an interactive system and a method for encoding, e.g. position encoding, a touch by an object. The system comprises a display, a waveguide for guiding light, which waveguide is displaceable in relation to the display, a first light source for emitting light into the waveguide, and a detector for detecting light from the waveguide. The waveguide may be in a first position next to the display, and in a second position displaced in relation to the display. When the waveguide is in the first position, a first surface of the waveguide is a touch-sensitive surface, such that the object touching the first surface disturbs at least a part of the light from the first light source, the disturbance of the light being detectable at the detector. Thus, encoding of the touch is enabled.

摘要： A method and an apparatus for measuring the rotational movement of objects or the vorticity by means of electromagnetic coherent radiation. In the radiation path from a laser (1) an optical element (6) is arranged, e.g. a grating or a birefringent prism, dividing the beam into two radiation beams which by means of a lens (8) irradiate the object (9) in two closely adjacent spots (10, 11). Scattered radiation from each of the spots is collected by the lens (8) and is sent as two separate return beams back through the same optical element (6) and then deflected towards a detector (14) in the output signal of which a signal frequency is present, which is the difference between the Doppler frequencies produced by the movement of the spots (10, 11), and which is proportional to the rotational velocity of the object (9). The described measuring method is simple and stable and self-compensating with respect to small errors originating from an optically not absolutely correct position of the optical elements.
