    摘要： In an optical input device based on movement of an object (15) and the device relative to each other and which comprising at least one optical sensor unit including a laser (3) having a laser cavity for generating a measuring beam (13), converging means (50) for converging the measuring beam in an action plane and for converging measuring beam radiation reflected by the object in the laser cavity to generate a self-mixing effect in the laser and measuring means for measuring the result of the self-mixing effect, which effect is determined by said movement, the converging means (50) is adapted to provide a self-mixing effect that is smaller than a possible maximum but larger than a detection threshold for an extended range of distances (ΔZ) between the object and the device. This allows obtaining the required self-mixing effect in an extended range of distances between the object and the device.

    摘要： An optical input device for an apparatus generates input signals by moving the device and an object (15) relative to each other and measures the movement by the effects of self-mixing in a diode laser (3, 5) and Doppler shift caused by the movement. For each measuring axis (X, Y, Z), radiation from a diode laser (3, 5) is converged on a window (12) across which the object (15) moves. Part of the radiation scattered by the object, whose frequency is Doppler-shifted due to the movement, re-enters the laser cavity (20) and causes a change in cavity properties. By measuring such a change, for example, by a photo diode, information about the movement is obtained. As the input device is small and cheap, it can be used in a number of different consumer apparatus.

    摘要： In an apparatus for handling sheet material or an optical input device, for example, which employs a relative movement sensor (108) utilizing the so-called “self-mixing” effect of a laser diode, a band pass filter (100) is provided for filtering the electric signal resulting from measurement of the electric signal to reduce or substantially eliminate the effects of both the low frequency carrier signal and the high frequency noise present in such a signal. As a result, the precision of the laser self-mixing translation measurements is significantly improved.

    摘要： The invention relates to a device having touch sensitivity functionality, comprising a surface (2), touch-sensitive means (5) for detecting the presence of a touch input member (6) being in contact with or close to the surface (2) generating a distance sensor signal. Since conventional resistive or capacitive touch-sensitive layers have a limited transparency, they significantly reduce the screen quality. According to the invention, a display device having touch sensitivity functionality is provided without adding a layer to the display, and is characterized in that the touch-sensitive means (5) comprises means (51) for emitting a laser beam (4, 8) in a plane parallel and close to the surface (2), said laser beam being periodically deflected across the entire surface (2), and means (51, 60) for receiving the light reflected or scattered from the touch input member (6) generating said distance sensor signal therefrom.
