Problems solved by technology

[0007] Such techniques have the disadvantage that the curvature of the fibers is relatively limited
In addition, it may be difficult to implement the optical system in such a way as to avoid beam divergence of the laser light emerging from the end of the fiber

Abstract

A device (100) comprises at least two fiber-shaped elements (101-103), which are arranged between a fastening means (141) and a deflecting unit (142). The deflecting unit (142) is designed to deflectlight (146). The device (100) also comprises an actuator, which is designed to induce at least one degree of freedom of the motion of the at least two fiber-shaped elements (101-103).

Description

technical field [0001] Various examples of the invention relate generally to fiber scanners configured to deflect light. Various examples of the invention relate in particular to a device having at least two fiber-shaped elements arranged between the fastening device and the deflection unit. Background technique [0002] Distance measurements to objects are desired in a variety of technical fields. For example, in the context of autonomous driving applications, it may be desirable to detect objects in the vehicle's surroundings, and in particular to determine distances to objects. [0003] One technique for distance measurement of objects is the so-called LIDAR technique (Light Detection and Ranging; sometimes also LADAR). Here, pulsed laser light is emitted by an emitter. Objects in the surrounding environment reflect the laser light. Subsequently, these reflections can be measured. By determining the travel time of the laser light, the distance to the object can be de...
