A movable fiber (201) has a first degree of freedom of movement and a second degree of freedom of movement. An actuator is equipped to induce a first movement of the fiber corresponding to the first degree of freedom during a period of time and to induce a second movement of the fiber corresponding to the second degree of freedom superimposed on the second movement. An optional LIDAR system is equipped to carry out a distance measurement of objects based on the laser light in the surroundings of the device with a plurality of pixels. The pixels are arranged in a two-dimensional image area which is defined by the first movement and the second movement during the period of time. The first movement has a variable amplitude during the period of time.
