3D Image Sensor REAL3™
Time-of-Flight provides accurate and robust depth data
Measure your surrounding in 3D with a Time-of-Flight (ToF) camera. ToF technology is sunlight robust, highly scalable, and ready for integration into numerous consumer electronic, automotive and industrial applications.
REAL3™ is Infineon's Time-of-Flight based 3D image sensor family consisting of highly integrated single-chip imagers manufactured in an ToF optimized CMOS process.
REAL3™ is the basis for the worldwide smallest 3D ToF camera module and the first 3D depth sensor being integrated in commercially available smartphones.

Time-of-Flight Principle & Benefits
Time-of-flight technology is directly measuring the depth and amplitude information in every pixel by using only one infrared flash light source. The modulated infrared light is emitted to the whole scenery and the reflected light is captured by the ToF imager. The measured phase difference between emitted and received light as well as the amplitude values are resulting into highly reliable distance information and a grey scale picture of the complete scene simultaneously.
This principle keeps the power consumption at a minimum and provides fast data acquisition for real-time operation. Also, the required depth data processing for ToF is known to be less demanding than for other algorithm intensive depth sensing technologies like structured light or stereovision, saving additionally power at the application processor.
An inherent benefit of the time-of-flight technology is the simple and robust design of a ToF camera module. It consists of only two key components, the imager and one single flash illumination component, without the need of any mechanical baseline. This results in very small camera modules with high integration flexibility into demanding applications like a mobile phone and a lean and fast calibration procedure for easy and robust mass production.

REAL3™ Image Sensor Family
The REAL3™ image sensor family consists of highly integrated 3D Time-of-Flight imager. The ToF sensors have been jointly developed by Infineon and pmdtechnologies AG. They embed a high performance ToF pixel-matrix from pmd and are manufactured in Infineon’s volume-proven ToF optimized CMOS process. The high level of integration, the unique performance and the manifold features enable most accurate and reliable depth data and smallest camera module designs.

Infineon co-developed the 3D image sensor family REAL3 with pmdtechnologies AG from Siegen, Germany. Both companies are jointly providing the technical support for camera module makers. The contribution of pmdtechnologies to the REAL3 chip family is the ToF pixel matrix. Infineon contributes all functional blocks for the system-on-chip (SoC) integration and developed the ToF optimized CMOS manufacturing process.
REAL3™ for Consumer Applications
The monocular camera architecture and the compact REAL3 single-chip design enable smallest form factor camera modules and a robust integration into mobile devices. There is no need for a mechanical baseline or any risk of de-calibration in the field. The high performance of the REAL3 imager with its unique Suppression of Background Illumination (SBI) circuitry ensures robust operation in strong sunlight with a minimum of power – all mandatory requirements of battery driven applications.
REAL3 is the first 3D depth sensing technology integrated into commercially available Tango enabled smartphones, Google’s technology to give mobile devices a human-scale understanding of space and motion.
