| 英文摘要 | The invention describes a VCSEL array (100) comprising two, three, four or more VCSELs (130) arranged on a common semiconductor substrate (101), wherein the VCSEL array (100) further comprises one common optical structure (140) integrated on wafer level, wherein the common optical structure (140) is arranged to transform the laser light (10) to transformed laser light (150) such that a continuous illumination pattern (20) can be provided in the reference plane, wherein the common optical structure (140) is arranged to increase a size of the illumination pattern (20) in comparison to an untransformed illumination pattern which can be provided without the common optical structure (140), and wherein the common optical structure (140) is further arranged such that each VCSEL (130) is arranged to illuminate a sector (21) of the illumination pattern (20), wherein each sector (21) is smaller than the illumination pattern (20). The invention further describes a lighting device comprising such a VCSEL array (100), a time-of-flight camera (200) comprising such a lighting device and a method of manufacturing the VCSEL array (100). |
