Abstract
(EN)
Embodiments of the disclosure provide an apparatus for adjusting a light beam that includes a microelectromechanical system (MEMS), a non-MEMS system. The MEMS may include: an array of first rotatable mirrors to receive and reflect the light beam and an array of first actuators configured to rotate each rotatable mirror of the array of first rotatable mirrors. The non-MEMS system may include a second adjustable mirror to receive and reflect the light beam and a second actuator configured to adjust the second adjustable mirror. The light beam received by the array of first rotatable mirrors is the light beam reflected by the second adjustable mirror or the light beam received by the second adjustable mirror is reflected by the array of first rotatable mirror.

Des modes de réalisation de l'invention concernent un appareil pour ajuster un faisceau lumineux qui comprend un système microélectromécanique (MEMS) et un système non-MEMS. Le MEMS peut comprendre : un réseau de premiers miroirs rotatifs pour recevoir et réfléchir le faisceau lumineux et un réseau de premiers actionneurs configurés pour faire tourner chaque miroir rotatif du réseau de premiers miroirs rotatifs. Le système non-MEMS peut comprendre un second miroir réglable pour recevoir et réfléchir le faisceau lumineux et un second actionneur configuré pour ajuster le second miroir réglable. Le faisceau lumineux reçu par le réseau de premiers miroirs rotatifs est le faisceau lumineux réfléchi par le second miroir réglable, ou le faisceau lumineux reçu par le second miroir réglable réfléchi par le réseau de premiers miroirs rotatifs.
