ams OSRAM AQAA-20 BELAGO 1.1 Dot Projector

ams OSRAM AQAA-20 BELAGO 1.1 Dot Projector is a proprietary infrared dot-pattern illuminator for stereoscopic imaging and structured light platforms with an eye-safety feature. It produces a focus-free, high-contrast dot pattern that algorithms can use to address low-texture situations and achieve high-accuracy depth maps. An additional benefit of the dot pattern is a reduction of the computational load required to perform the depth calculation. The ams OSRAM AQAA-20 BELAGO 1.1 dot-pattern illuminator is provided in a miniature package that is compatible with standard lead-free reflow processes. As such, it can be successfully used onboard a great variety of 3D sensing platforms, from mobile to IoT to robotics, both for stereoscopic imaging and structured light. AQAA-20 BELAGO 1.1 emitters project 5k dots, focus-free, in a random pattern at 940nm.
