Dot-Pattern Infrared Illuminator for 3D Stereoscopic Imaging v2-00 • 2019-May-15 Abstract The BELICE infrared illuminator is the most compact dot-projector for stereoscopic imaging available today. It produces a very high-contrast dot pattern that stereo-matching algorithms can use to mitigate the problem of lack of texture, and to produce high-accuracy depth maps. BELICE enables active stereoscopic imaging to be implemented on a variety of platforms, from robotics to mobile devices.

1 General Description
1.1 Key Benefits & Features
Stereoscopic imaging systems, however, often suffer from impaired performance when the scene lacks features: an example is a flat, smooth surface such as a wall. In such cases, the 3D information captured by stereoscopic imaging systems is typically incomplete or inaccurate. Furthermore, the search for features in the images often results in high computational loading. Now ams has developed a unique, proprietary solution to this problem. The BELICE infrared illuminator, the most compact dot-projector for stereoscopic imaging available today, produces a very high-contrast dot pattern that stereo-matching algorithms can use to mitigate the problem of lack of texture, and to produce high-accuracy depth maps. The presence of the infrared pattern also reduces considerably the computational load imposed by the software, as it offers many features to facilitate matching of the left and right images. BELICE enables active stereoscopic imaging to be implemented on a variety of platforms, from robotics to mobile devices. The benefits and features of BELICE-850, Dot-Pattern Infrared Illuminator for 3D Stereoscopic Imaging, are listed below: Figure 1: Added Value of Using BELICE-850 Benefits Features Small package size 3.4mm x 3.5mm x 3.56mm Module height compatible with integration in mobile platforms 3.56mm ± 0.1 Power efficient High optical efficiency, high VCSEL efficiency Easy component mounting Standard lead-free solder reflow compatible High contrast dot pattern Optimized for active stereo vision

6.2 Imaging Setup
For the pattern characterization, the output is projected onto a white, matte-finished target board (Lambertian surface), at a distance. Images are taken inside a dark chamber with a monochrome CCD camera and a wide angle objective.
6.3 Hotspot Detection
Every individual BELICE emitter is inspected during production to detect the presence of hotspots and similar non-uniformities that cause excessive brightness of the infrared pattern and could be harmful to the human eye.

10 Soldering & Storage Information
BELICE modules have been tested for lead-free solder reflow compatibility with peak temperatures up to 250°C (MSL3). An example reflow profile is provided in Figure 19. The exact reflow profile may depend on exact solder used. An example of solder paste that can be used is Tamura LFSOLDER TLF-204-NH(20-38). Figure 19: Solder Reflow Profile Graph Attention It is not advised to proceed to cleaning after SMT reflow process. The modules MUST NOT be cleaned using ultrasonic cleaning. We suggest to use flux free solder paste and not to clean after SMT. In case a cleaning is un-avoidable, rinse with DI water, followed by a 2h bake @70°C.
