How does ToF work?
Time of flight (ToF) technology projects a single modulated, infrared light source onto an object, user or scene of interest. The reflected light is captured by the ToF imager, which measures depth, amplitude and phase difference per pixel. The result is a highly reliable image of the distance or depth plus a gray-scale picture of the entire scene.
Time of flight (ToF) supports real-time sensing thanks to rapid data acquisition. In addition, it minimizes power consumption as ToF depth data processing is less compute-intensive than other depth-sensing technologies like structured light or stereovision. This reduces the application processor power drain.
Other REAL3™ highlights include simple and robust ToF camera module designs. The outstanding imager performance and proven sunlight robustness due to the patented Suppression of Background Illumination (SBI) circuitry in every pixel reduces the active light required to a minimum. So camera modules only need two key components: the imager and a flash illuminator. No mechanical baseline is required. This results in very compact camera modules with high integration flexibility to support demanding applications. Our REAL3™ technology also enables fast, lean calibration for easy and robust mass production.

3D reference cameras
To evaluate REAL3™ Time-of-Flight technology, various 3D reference cameras are available. The CamBoard pico family is designed by our development partner pmdtechnologies. These reference cameras come with a powerful SDK providing a high-quality depth map for evaluation and application software development. For consumer mobile applications, the CamBoard picoflexx camera is the product of choice as it can be easily integrated into a mobile device. The CamBoard pico flexx features flexible working ranges, flexible frame rates, Android support, MacOS support and reduced depth noise.

Cooperation between Infineon and pmdtechnologies
Infineon co-developed the 3D image sensor family REAL3™ in collaboration with pmdtechnologies AG, based in Siegen, Germany. Both partners are providing joint technical support for camera module makers. pmdtechnologies contributed the ToF pixel matrix to the REAL3™ chip family, whereas Infineon contributed all the functional blocks required for system-on-chip (SoC) integration, and also developed the ToF-optimized CMOS manufacturing process.
