Patent ID: 11320661

Abstract:
A device for alternating between different shapes of a light beam includes a multi-plane light conversion (MPLC) device that is used to apply a unitary transformation to a light beam by way of a succession of elementary transformations. The MPLC faces the light source so that the light beam is emitted into the MPLC device along a reference axis. The device further includes automated means arranged upstream of the multi-plane light conversion (MPLC) device for varying the transverse position and/or the angle of incidence of the light beam in relation to the reference axis and/or to vary the angle of rotation of the light beam about the reference axis. The MPLC device is designed to transform a variation of the transverse position and/or the angle of incidence and/or the angle of rotation of the light beam into a modification of the specific shape of the light beam.
