Abstract: Optical apparatus includes a shaft, which is configured to rotate about an axis of the shaft relative to a base. A mirror is fixed to the shaft so that the mirror rotates about the axis. A rotor including a permanent magnet is fixed to rotate with the shaft. A stator is configured to generate a magnetic field having a DC component in a vicinity of the rotor. A torsion spring, extending along the axis, has a first end that is attached to rotate with the shaft and a second end attached to the base.

Abstract: A display system may display image frames. The system may include multiple sets of laser dies. Each set of laser dies may emit a respective set of beams of light to a photonic integrated circuit. Each set of beams may include light in at least three wavelength ranges that include visible and/or infrared wavelengths. Channels in the photonic integrated circuit may receive the sets of beams with a first pitch and may emit the set of beams with a second pitch that is finer than the first pitch and at a given angular separation to tangential and sagittal axis scanning mirrors.

Abstract: Scanning apparatus includes a base and a gimbal, including a shaft that fits into rotational bearings in the base and is configured to rotate through 360° about a gimbal axis relative to the base. A mirror assembly, fixed to the gimbal, includes a mirror, which is positioned on the gimbal axis and is configured to rotate about a mirror axis perpendicular to the gimbal axis. A transmitter directs pulses of optical radiation toward the mirror, which directs the optical radiation toward a scene. A receiver, receives, via the mirror, the optical radiation reflected from the scene and outputs signals in response to the received radiation. Control circuitry drives the gimbal to rotate about the gimbal axis and the mirror to rotate about the mirror axis, and processes the signals output by the receiver in order to generate a three-dimensional map of the scanned area.

Abstract: Optical apparatus (64) includes a stator assembly (47), which includes a core (78, 90, 91) containing an air gap and one or more coils (80, 92, 94, 116, 120) including conductive wire wound on the core so as to cause the core to form a magnetic circuit through the air gap in response to an electrical current flowing in the conductive wire. A scanning mirror assembly (45, 83, 85, 130) includes a support structure (68), a base (72), which is mounted to rotate about a first axis relative to the support structure, and a mirror (46), which is mounted to rotate about a second axis relative to the base. At least one rotor (76, 132) includes one or more permanent magnets, which are fixed to the scanning mirror assembly and which are positioned in the air gap so as to move in response to the magnetic circuit. A driver (82) is coupled to generate the electrical current in the one or more coils.

Abstract: Optical systems that may, for example, be used in light ranging and detection (LiDAR) applications, for example in systems that implement combining laser pulse transmission in LiDAR and that include dual transmit and receive systems. Receiver components of a dual receiver system in LiDAR applications may include a medium range (50 meters or less) receiver optical system with a medium entrance pupil and small F-number and with a medium to wide field of view. The optical system may utilize optical filters, scanning mirrors, and a nominal one-dimensional SPAD (or SPADs) to increase the probability of positive photon events.

Abstract: A scanning device includes a substrate, which is etched to define a recess in the substrate and to define the following structures contained in the recess: At least first and second mirrors are disposed along a common axis of rotation. Torsion hinges extend collinearly along the axis of rotation and connect the first and second mirrors to the substrate so that the first and second mirrors rotate on the torsion hinges about the axis of rotation. Rigid struts are disposed alongside the axis of rotation and connect the first mirror to the second mirror so that the struts rotate about the axis of rotation together with the first and second mirrors.

Abstract: Optical systems that may, for example, be used in remote sensing systems, for example in systems that implement combining laser pulse transmission in LiDAR and that include dual transmit and receive systems. A dual receiver system may include a receiver including an optical system with a relatively small aperture and wide field of view for capturing reflected light from short-range (e.g., 20 meters) objects. The optical systems may refract the reflected light to photodetectors (e.g., single photo-avalanche detectors (SPADs)) that capture the light. Light captured at the photodetectors may, for example, be used to determine range information for objects or surfaces in the environment.

Abstract: A scanning device includes a substrate, which is etched to define an array of two or more parallel rotating members and a gimbal surrounding the rotating members. First hinges connect the gimbal to the substrate and defining a first axis of rotation, about which the gimbal rotates relative to the substrate. Second hinges connect the rotating members to the support and defining respective second, mutually-parallel axes of rotation of the rotating members relative to the support, which are not parallel to the first axis.
