3D Sensing

ams is the only company that offers infrared illumination solutions for all these 3D camera platforms. Based on our state-of-the art Vertical Cavity Surface Emitting Laser (VCSEL) technology and our optical design and packaging capabilities, we provide unique solutions for all 3D sensing cameras: dot-pattern illuminators for structured light cameras as well as texture enhancement for stereo cameras, and a wide range of flood illuminators for ToF and video capture.


We complement our VCSEL illuminators with software and system-level components to assist in the deployment of 3D cameras. Our solutions are used in a variety of consumer electronic platforms such as face recognition applications for mobile devices, gesture and people recognition for home systems, robotics navigation, and Advanced Driver-Assistance Systems (ADAS) for automotive.

Stereoscopic Imaging

Most stereoscopic imaging platforms use two cameras at different angles to capture images. Image-processing software identifies common features in both images and extract distance information following a triangulation method. A common issue in stereoscopic imaging is encountered when the scene lacks features (non-textured surfaces such as walls) which causes the 3D information to become incomplete or inaccurate. Furthermore, the search for features in the images often results in high computational load. ams AG has developed a unique, proprietary solution to effectively address these issues: the BELICE infrared illuminator is the most compact dot-projector for stereoscopic imaging available on the market today. It produces a very high-contrast dot pattern that stereo-matching algorithms can use to solve low-texture issues and achieve high-accuracy depth maps. The presence of the infrared pattern also reduces considerably the computational load required by the software, as it offers many features for matching the left and right images. BELICE enables stereoscopic imaging to be implemented on a variety of platforms, from robotics to mobile devices.

Structured Light Illumination

In a structured light camera, the infrared illuminator plays a critical role for 3D sensing: it projects a pre-determined, or “encoded,” pattern onto the scene, which can be “decoded” by specific algorithms to extract depth information over the entire image.

Flood Illumination

A time-of-flight camera requires a uniform, high-frequency modulated infrared light to be projected onto the scene. The time-of-flight sensor is carefully synchronized with the illuminator and utilizes the light that is reflected by objects in the scene to determine the distance to these objects. The TARA family of flood-illuminators is designed for a great variety of time-of-flight cameras: from TARASLIM, which is optimized for bezel-less mobile platforms performing face recognition tasks, to TARA2000, which addresses wide-angle gesture-sensing and head-tracking applications in various market segments such as home robotics and automotive.
