1. An illumination module, comprising:
an array of vertical cavity surface emitting lasers (VCSELs) emitting light, wherein at least one VCSEL in the array of VCSELs comprises a multi junction VCSEL;
a driver configured to provide current to the array of VCSELs; and
an optical element configured to receive the light emitted by the array of VCSELs and output a light pattern from the illumination module;
wherein the array of VCSELs is segmented into a first segment of VCSELs configured to emit light and a second segment of VCSELs configured to detect light emitted by the first segment of VCSELs.
