    Abstract: Methods and apparatus for measuring objects comprise a plurality of light sources to generate a plurality of light beams directed toward a spot generator array comprising a plurality of spot generating lenses. The plurality of light sources is separated from the spot generator array with a separation distance sufficient to overlap the plurality of light beams at each of the spot generating lenses. The overlap of each of the beams at each of the spot generating lenses provides smoothing of the energy profile of the light energy incident on the spot generating lenses. The spot generator array generates focused spots comprising overlapping focused beams. The overlapping beams may comprise overlapping beams of a vertical cavity surface emitting laser (VCSEL) array, and the overlapping focused beams can decrease optical artifacts.

    Abstract: An apparatus and method for two-dimensional wavelength beam combining of a plurality of laser sources. In one embodiment, an external cavity multi-wavelength laser comprises an array of laser gain elements, two optical transform lenses, two dispersive elements, an imaging system, a deflective array, and an output coupler. First and second optical transform lenses spatially overlap optical beams in first and second dimensions forming regions of overlap at the first and second dispersive elements. The deflective array comprises a plurality of mirrors wherein each mirror deflects and rearranges the optical beams from a common row. The dispersive elements introduce wavelength discrimination that when combined with the output coupler, provide the required feedback gain. The output coupler creates a single output port for the plurality of external optical cavities established in unison with the plurality of laser emitters. The output coupler transmits a multi-wavelength output beam comprising spatially overlapped coaxial optical beams.

    Abstract: A depth camera includes an illumination module and an image detector module. The illumination module outputs structured light that illuminates a capture area. The image detector module captures an image of the structured light as reflected from object(s) within the capture area. The illumination module includes a VCSEL array and optical element(s), such as projection optics, an MLA or DOE, or combinations thereof. Projection optics receive a light pattern emitted by the VCSEL array and project the light pattern. An optical element, downstream from the projection optics, can cause a total number of features included in the structured light to be greater than the number of features included in the light pattern projected by the projection optics. In an embodiment, a pitch of an MLA is offset relative to a pitch of the VCSEL array. Various structures can include alignment elements to aid manufacture of the illumination module.
