Abstract
The present invention discloses a VCSEL array that can function in at least two different operational modes. In one operational mode, the VCSEL array functions as a regular-patterned array; and in the other operational mode, the VCSEL array functions as an irregular-patterned array. Thus, the same VCSEL chip may be used as an illumination light source or a structural light method light source for 3D sensing, depending on the selected operational mode.
