Summary:A structured light source comprising VCSEL arrays is configured in many different ways to project a structured illumination pattern into a region for 3 dimensional imaging and gesture recognition applications. One aspect of the invention describes methods to construct densely and ultra-densely packed VCSEL arrays with to produce high resolution structured illumination pattern. VCSEL arrays configured in many different regular and non-regular arrays together with techniques for producing addressable structured light source are extremely suited for generating structured illumination patterns in a programmed manner to combine steady state and time-dependent detection and imaging for better accuracy. Structured illumination patterns can be generated in customized shapes by incorporating differently shaped current confining apertures in VCSEL devices. Surface mounting capability of densely and ultra-densely packed VCSEL arrays are compatible for constructing compact on-board 3-D imaging and gesture recognition systems.
