摘要	A vertical cavity surface emitting laser (VCSEL) array may comprise a first subset of VCSELs of a plurality of VCSELs, and a second subset of VCSELs of the plurality of VCSELs. One or more first beams to be emitted by the first subset of VCSELs, when the VCSEL array is powered, and one or more second beams to be emitted by the second subset of VCSELs, when the VCSEL array is powered, may have different patterns of areas of energy intensity. The different patterns of areas of energy intensity may include respective areas of high energy intensity and respective areas of low energy intensity.
其他摘要	垂直腔表面发射激光器（VCSEL）阵列可以包括多个VCSEL的第一VCSEL子集，以及多个VCSEL的第二VCSEL子集。当VCSEL阵列被供电时，由VCSEL的第一子集发射的一个或多个第一光束，以及当VCSEL阵列被供电时由第二VCSEL子集发射的一个或多个第二光束可具有不同的能源强度的区域。能量强度区域的不同模式可以包括高能量强度的相应区域和低能量强度的相应区域。
