Claim Text:
1. Mapping apparatus, comprising: 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, comprising at least one rotating mirror, which is configured to rotate while the transmitter directs the at least two beams to reflect from the at least one rotating mirror so as to scan the two or more beams in the raster pattern over a scene; a receiver, comprising a detector which is configured to receive, via reflection from the at least one mirror, the light reflected from the scene as the at least one mirror rotates, and to generate an output indicative of a time of flight of the pulses to and from points in the scene; and a processor, which is coupled to process the output of the receiver so as to generate a 3D map of the scene.
