摘要
A stereoscopic optical system including: left and right channels; an electromagnetic actuator including a stator and rotor; wherein first optical components of the left channel are arranged in a left tube and second optical components of the right channel are arranged in a right tube; the stator is arranged outside the guide tubes; the rotor includes a left rotor, in which one or more of the first optical components is accommodated, and a right rotor, in which one or more of the second optical components is accommodated; the left and right rotors are mounted in one of the left and right tubes to be movable in a longitudinal axial direction; the left and right rotors include paramagnetic and/or ferromagnetic material and are movable by an electromagnetic field; the stator includes distal and proximal permanent magnets oppositely polarized; and the stator includes an electric coil for generating the electromagnet field.
