    Abstract: A microelectromechanical system (MEMS) mirror assembly may comprise a frame and a MEMS mirror coupled to the frame. The MEMS mirror assembly may also include at least one piezoelectric actuator including a body and a piezoelectric element. When subjected to an electrical field, the piezoelectric element may be configured to bend the body, thereby moving the MEMS mirror with respect to a plane of the frame. The MEMS mirror assembly may further include at least one heating resistor configured to heat the piezoelectric element when an electric current passes through the at least one heating resistor.

    Abstract: A deflector unit for a light scanning system includes a mirror and at least one actuator arm. The actuator arm may include an anchor end and a coupler end. The at least one actuator arm may include an anchor end, a coupler end, and an actuator axis that extends from a first midpoint to a second midpoint, the first midpoint being a midpoint of an edge of the at least one actuator arm at the coupler end and the second midpoint being a midpoint of an edge of the at least one actuator arm at the anchor end, the mirror being coupled to the coupler end of the at least one actuator arm, wherein the mirror is configured to tilt about at least one tilting axis in response to a movement of the at least one actuator arm, and wherein a shortest distance of the mirror from the first midpoint is less than a shortest distance of the mirror from the second midpoint.

    Abstract: In some embodiments, a LIDAR system may include at least one processor configured to control at least one light source for projecting light toward a field of view and receive from at least one first sensor first signals associated with light projected by the at least one light source and reflected from an object in the field of view, wherein the light impinging on the at least one first sensor is in a form of a light spot having an outer boundary. The processor may further be configured to receive from at least one second sensor second signals associated with light noise, wherein the at least one second sensor is located outside the outer boundary; determine, based on the second signals received from the at least one second sensor, an indicator of a magnitude of the light noise; and determine, based on the indicator the first signals received from the at least one first sensor and, a distance to the object.
