摘要： An optical input and/or control de and/or actuating variable functions of, for examp device, the optical input and/or control device ha radiation from a diode laser (3) is converged. As across the window (12), part of the scattered radi due to the movement of the finger (15), re-enters measured using the self-mixing effect of the lase radiation emitted by the laser (3) and re-entering of the laser and thus in the radiation emitted by photo-diode (4) which converts the radiation vari circuitry is provided which processes this signal. ice for manually selectively controlling e, an image capture device or a computer mg a transparent window (12) on which an object, e.g. a user's finger (15), moves tion, whose frequency is Doppler-shifted the laser cavity.
