(54) Title (EN): MIRROR ASSEMBLY FOR LIGHT STEERING
(54) Title (FR): ENSEMBLE MIROIR DE GUIDAGE DE LUMIÈRE

(57) Abstract:
(EN): Methods and systems for light steering are proposed. In one example, an apparatus comprises: a light source; a receiver; a microelectromechanical system (MEMS) and a controller. The MEMS comprises: an array of first rotatable mirrors to receive and reflect the light beam from the light source and a second rotatable mirror to receive the light beam reflected by the array of first rotatable mirrors. The controller is configured to rotate, respectively, the array of first rotatable mirrors and the second rotatable mirror to set a first angle of light path with respect to a first dimension and to set a second angle of the light path with respect to a second dimension orthogonal to the first dimension to perform at least one of: reflecting light from the light source along the light path, or reflecting input light propagating along the light path to the receiver.
(FR): La présente invention concerne des procédés et des systèmes de guidage de lumière. Dans un exemple, un appareil comprend : une source de lumière; un récepteur; un système microélectromécanique (MEMS) et un dispositif de commande. Le MEMS comprend : un réseau de premiers miroirs rotatifs pour recevoir et réfléchir le faisceau lumineux provenant de la source de lumière et un second miroir rotatif pour recevoir le faisceau lumineux réfléchi par le réseau de premiers miroirs rotatifs. Le dispositif de commande est configuré pour tourner, respectivement, le réseau de premiers miroirs rotatifs et le second miroir rotatif pour régler un premier angle de trajet de lumière par rapport à une première dimension et pour régler un second angle du trajet de lumière par rapport à une seconde dimension orthogonale à la première dimension pour effectuer au moins l'une de : réfléchir la lumière provenant de la source de lumière le long du trajet de lumière, ou réfléchir la lumière d'entrée se propageant le long du trajet de lumière vers le récepteur.
