By introducing a Vertical Cavity Surface Emitting Laser (VCSEL)-based flood illuminator in a slim package, the company wants to push 3D sensing applications in mainstream mobile phones. The 2W Merano-PD is suitable for use in the latest technologies for 3D sensing, including the time-of-flight and structured light methods. Benefiting from optimized thermal design, the 2W-Merano-PD module measures 2.4×3.3×1.2mm for easy integration into a mobile phone’s design. The MERANO-PD emits pulsed bursts of invisible IR light. A separate IR light detector senses the sequence of reflections from objects in the field of illumination and renders them as a 3D depth map or scan. The
MERANO-PD may also be used in dot-pattern recognition (structured light) systems for 3D sensing, for flood illumination in IR cameras and for industrial 3D sensors and scanners. The 940nm IR output, as well as the illumination pattern, is precisely controlled in the pre-defined field of illumination for best system efficiency. The device also integrates a photodiode which detects impairment of the device’s diffuser. When linked to a separate monitoring circuit, this means that the mobile phone can disable the illuminator for eye-safety.
