Abstract (en)
[origin: WO2021115606A1] A dual actuation system (1) having one actuation axis (A) and comprising a first magnet (2), a second magnet (3), a first coil (4), and a second coil (5). The first magnet (2), the second magnet (3), the first coil (4), and the second coil (5) are arranged in an at least partially overlapping arrangement in a direction perpendicular to the actuation axis (A). Manipulating electrical current in the first coil (4) generates a first movement (M1) along the actuation axis (A) and manipulating electrical current in the second coil (5) generates a second movement (M2) along the actuation axis (A). The first movement (M1) and the second movement (M2) are generated independently of each other. By overlapping the coils and magnets of the dual actuation system, a very compact solution is provided, which has a positive influence on the form factor of the optomechanical system and the electronic device into which it is to be arranged.
