    Abstract: Optoelectronic apparatus includes a semiconductor die and a monolithic array of light-emitting elements formed on the semiconductor die in a grid pattern comprising multiple columns. Conductors formed on the die define a respective common contact for driving each column of the light-emitting elements. A diffractive optical element (DOE) is configured to project multiple replicas of a pattern of stripes generated by the light-emitting elements, each stripe corresponding to a respective one of the columns.

    Abstract: Mapping apparatus includes a transmitter, which is configured to emit, in alternation, at least two beams comprising pulses of light along respective beam axes that are mutually offset transversely relative to a scan line direction of a raster pattern. A scanner is configured to scan the two or more beams in the raster pattern over a scene. A receiver is configured to receive the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to process the output of the receiver so as to generate a 3D map of the scene.

    Abstract: A method for manufacturing includes forming on a surface of a metal master a pattern that defines an array of diffractive optical elements (DOEs). The pattern is replicated from the metal master onto a layer of a curable polymer that is deposited over a transparent substrate. The polymer in which the pattern has been replicated is cured, thereby setting the DOEs in the polymer. The transparent substrate is diced so as to singulate the DOEs.
