    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: Image projection apparatus includes an image generating assembly, which is configured to project a sequence of line images extending in a first direction. A scanning mirror is positioned to receive and to reflect the line images while rotating about a mirror axis parallel to the first direction. A pupil expander has an edge positioned to receive the line images reflected by the scanning mirror and a face extending in a second direction non-parallel to the first direction and to the edge, and which is configured to direct simultaneously through the face multiple, parallel replicas of the expanded line images arrayed along the second direction.

    Abstract: An optical device includes a transmitter, which emits a beam of optical radiation, and a receiver, which includes a detector configured to output a signal in response to the optical radiation. An active area of the detector has a first dimension along a first axis and a second dimension, which is less than the first dimension, along a second axis perpendicular to the first axis. An anamorphic lens, which collects and focuses the optical radiation onto the active area of the detector, has a first focal length in a first plane containing the first axis and a second focal length, greater than the first focal length, in a second plane containing the second axis. A scanner scans the beam across a target scene in a scan direction that is aligned with the first axis, and directs the optical radiation that is reflected from the target scene toward the receiver.

    Abstract: An optical device (20A, 20B, 100, 200, 800) includes a first array of emitters (28A, 28B) disposed on a semiconductor substrate (218) and configured to emit respective beams of optical radiation. A second array (36A, 36B, 224, 808) of micro-optics (34A, 34B, 226, 802) is positioned in alignment with the respective beams of the optical emitters and arranged to condition phases of the beams so that different ones of the beams are transmitted with different phase qualities

    Abstract: An optical apparatus includes an optically transparent slab waveguide including first and second, mutually-parallel planar faces and an edge non-parallel to the planar faces. A radiation source directs a beam of optical radiation to enter the waveguide through the first planar face at an entrance location and entrance angle selected so that the beam subsequently exits the waveguide at an exit location in a surface selected from among the second planar face and the edge. A scanning mirror is positioned to receive the beam that has exited through the surface and to reflect the beam back through the surface into the waveguide while the scanning mirror rotates about an axis parallel to the surface over a range of angles selected so as to cause the beam, after reflection back into the waveguide through the surface, to propagate within the waveguide by total internal reflection (TIR).

    Abstract: A display system may display image frames. The system may include a scanning mirror and an array of staggered light emitting elements. The light emitting elements may emit image light and collimating optics may direct the light at the scanning mirror, which reflects the image light while rotating about an axis. Control circuitry may selectively activate the light emitting elements across tangential and sagittal axes of the image frame while controlling the scanning mirror to scan across the sagittal axis.

    Abstract: An optical component includes a block of a transparent material, having a trapezoidal cross-section defined by first and second parallel, rectangular faces on mutually-opposing sides of the block and third and fourth faces oriented diagonally at opposing ends of the first and second faces. One or more planar, partially-reflecting layers extend within the block between the third and fourth faces in an orientation parallel to the first and second faces.
