1. A light-emitting device array comprising:
a first light-emitting device comprising a first light-emitting structure and a first beam shaping structure located on the first light-emitting structure, wherein the first beam shaping structure is configured to convert light emitted by the first light-emitting structure into a first structured light, and the first beam shaping structure comprises a first metasurface having a first top view shape;
a second light-emitting device comprising a second light-emitting structure and a second beam shaping structure located on the second light-emitting structure, wherein the second beam shaping structure is configured to convert light emitted by the second light-emitting structure into a second structured light, and speckle patterns and spatial distributions of the first structured light and the second structured light on a projection plane are the same, and the second beam shaping structure comprises a second metasurface having a second top view shape that is the same as the first top view shape;
a third light-emitting device comprising a third light-emitting structure and a third beam shaping structure located on the third light-emitting structure, wherein the third beam shaping structure is configured to convert light emitted by the third light-emitting structure into a third structured light, and a speckle pattern and a spatial distribution of the third structured light and the speckle pattern and the spatial distribution of the first structured light on the projection plane are different, and the third beam shaping structure comprises a third metasurface having a third top view shape that is different from the first top view shape; and
a submount carrying the first light-emitting structure, the second light-emitting structure, and the third light-emitting structure, wherein the first beam shaping structure and the third beam shaping structure are respectively located on two corners of the submount passed by a diagonal line, and the first beam shaping structure and the second beam shaping structure are respectively located on two adjacent corners of the submount.
