摘要	A VCSEL projector and method for using the same are disclosed. In one embodiment, the apparatus comprises a vertical cavity surface emitting laser (VCSEL) array comprising a plurality of VCSELs; a micro-lens array coupled to the VCSEL array and having a plurality of lenses, and each of the plurality of lenses is positioned over a VCSEL in the VCSEL array; and a projection lens coupled to the micro-lens array (MLA), where light emitted by the VCSEL array is projected as a sequence of patterns onto an object by the projection lens.
其他摘要	公开了一种VCSEL投影仪及其使用方法。在一个实施例中，该装置包括垂直腔表面发射激光器（VCSEL）阵列，其包括多个VCSEL;微透镜阵列，耦合到VCSEL阵列并具有多个透镜，并且所述多个透镜中的每一个位于VCSEL阵列中的VCSEL上方;投影镜头耦合到微透镜阵列（MLA），其中由VCSEL阵列发射的光被投影透镜作为一系列图案投影到物体上。
