Abstract: 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.

Abstract: A miniature structured light illuminator is provided. The miniature structured light illuminator uses a semiconductor surface emitting array including VCSEL or RC-LED array and an array of microlens elements to generate a wide range of structured light illumination patterns. The emission beam from a surface emitter array may be selectively directed, steered, focused or expanded, by applying a lateral displacement of the microlens array, such that centers of the emission beam and microlens array are misaligned. Emitted beams may be directed through small optical components to project the structured light pattern to a distant plane. The surface emitting arrays may be configured in addressable form to be activated separately for continuous or pulsed operation with very fast pulses having

Abstract: A miniature illuminator is described which is suitable for assembly into mobile electronics devices such as cell phones and computer tablets. Features of the invention overcome the complexity of current miniature illuminators by using single molded structure which includes all the electrical feedthrough connections and has the features necessary for accurate mounting of optical components. The molded structure includes laser safety connections which provide an electrical interrupt signal when the illuminator is damaged in a way that could result in propagation of non-eye safe illuminator beams. In an alternate operation the illuminator provides a signal when a subject gets too close to the illuminator and would receive unsafe VCSEL illuminator beam. The laser safety feature is integrated into the molded Illuminator package so that separate electrically connected structures to achieve this function are eliminated.
