Abstract
A light-emitting device array includes a first light-emitting device, a second light-emitting device, and a third light-emitting device. A first beam shaping structure of the first light-emitting device is configured to convert light emitted by a first light-emitting structure of first light-emitting device into first structured light. A second beam shaping structure of the second light-emitting device is configured to convert light emitted by a second light-emitting structure of second light-emitting device into second structured light. Speckle patterns and spatial distributions of the first structured light and the second structured light on a projection plane are the same. A third beam shaping structure of the third light-emitting device is configured to convert light emitted by a third light-emitting structure of third light-emitting device into third structured light.
