Abstract:
An actuation system is proposed for an optical system, comprising a voice coil motor for actuating the optical system, the voice coil motor comprising a magnet and an electric coil, a position measuring unit for measuring the position of the electric coil and providing a position feedback signal, and a control unit for closed loop control of the position of the optical system based on a target position and the position feedback signal, used for generating a drive signal for the electric coil. According to the disclosure, a ferromagnetic element is arranged in proximity to the electric coil so that the inductance of the electric coil depends on its position. Further, the position-measuring unit measures the inductance of the electric coil and determines the position of the electric coil based on the determined inductance.

Claim (Index 1):
An actuation system for an optical system, comprising:\n a voice coil motor for actuating the optical system, the voice coil motor comprising at least one magnet and an electric coil; a position-measuring unit for measuring a position of the electric coil and providing a position feedback signal; and a control unit for closed loop control of a position of the optical system based on a target position and the position feedback signal, and for generating a drive signal for the electric coil, wherein a ferromagnetic element is arranged in proximity to the electric coil so that an inductance of the electric coil depends on its position, and the position measuring unit measures the inductance of the electric coil and determines the position of the electric coil based on a determined inductance.
