A light path adjustment mechanism includes a support, a carrier, an optical plate member and a plurality of actuators. The carrier is disposed on the support and connected to the support via a first elastic member and a second elastic member. The carrier includes a first side, a second side opposite the first side, a third side and a fourth side opposite the third side, and each of the third side and the fourth side is located between the first side and the second side.

An electro-mechanical device includes a payload of a magnet affixed to a mirror, and a coil assembly. The coil assembly has a body with wound electrically conducting wires and a payload aperture through which the payload travels. When voltage is applied to the coil assembly, current through the coil assembly generates a magnetic field resulting in a net upward force on the magnet that accelerates the payload to travel upward through the payload aperture for the mirror to block an optical pulse. As the magnet travels through the payload aperture, due to a magnetization direction of the magnet and a magnetic field in an upper portion of the coil assembly, the magnet experiences a net deceleration force that arrests the payload.
