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 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.

Abstract: A beam generating device includes a semiconductor substrate, having an optical passband. A first array of vertical-cavity surface-emitting lasers (VCSELs) is formed on a first face of the semiconductor substrate and are configured to emit respective laser beams through the substrate at a wavelength within the passband. A second array of microlenses is formed on a second face of the semiconductor substrate, with the microlenses in respective alignment with the VCSELs so as to transmit the laser beams generated by the VCSELs.

Abstract: Embodiments of the invention provide apparatus and methods for interactive reality augmentation, including a 2-dimensional camera and a 3-dimensional camera, associated depth projector and content projector, and a processor linked to the 3-dimensional camera and the 2-dimensional camera. A depth map of the scene is produced using an output of the 3-dimensional camera, and coordinated with a 2-dimensional image captured by the 2-dimensional camera to identify a 3-dimensional object in the scene that meets predetermined criteria for projection of images thereon. The content projector projects a content image onto the 3-dimensional object responsively to instructions of the processor, which can be mediated by automatic recognition of user gestures.

Abstract: Scanning apparatus includes a scanner, which is configured to scan over a field of view falling within a predefined angular range. An interference filter is positioned between the scanner and the field of view and is configured to pass light within a predefined wavelength range that is incident on the interference filter at angles within the predefined angular range, while reflecting the light within the predefined wavelength range that is incident on the interference filter at an angle that is outside the predefined angular range. An ancillary optical element communicates optically with the scanner at a wavelength within the predefined wavelength range via a beam path that reflects from the interference filter at the angle that is outside the predefined angular range.

Abstract: Optical apparatus includes first and second diffractive optical elements (DOEs) arranged in series to diffract an input beam of radiation. The first DOE is configured to apply to the input beam a pattern with a specified divergence angle, while the second DOE is configured to split the input beam into a matrix of output beams with a specified fan-out angle. The divergence and fan-out angles are chosen so as to project the radiation onto a region in space in multiple adjacent instances of the pattern.
