New i-ToF imager from Infineon and pmd

Munich, Germany – 24 February, 2023 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY), in collaboration with 3D time-of-flight specialist and premium partner pmdtechnologies, introduces the IRS2976C Time of Flight (ToF) VGA sensor, a performance-enhancing evolution of the IRS2877C ToF VGA sensor and novel member of the REAL3™ product family.

The implementation of Infineon's advanced pixel technology enables the pixels to achieve a quantum efficiency of 30 percent and more, a level so far only attained by back-side illumination (BSI) sensors. Remarkably, this is accomplished while maintaining the superior cost advantage of front-side illumination (FSI) sensors. As a result, the IRS2976C sensor is the first ToF imager in the world to pass Googles Class 3 (Strong) certification for face ID, while seamlessly operating under the mobile device’s display.

The IRS2976C imager supports a number of long-range, low-power use cases that enable a measurement range of 10 meter and further. As with all members of the REAL3™ family, pmdtechnologies' patented Suppression of Background Illumination (SBI) technology is integrated into each pixel. This provides the robust data in high dynamic range (HDR) and sunlight scenes.

“Our unique ToF CMOS process ensures excellent sensitivity and robust operation in indoor and outdoor environments,” said Christian Herzum, Vice President 3D-sensing at Infineon. “In addition, our IRS2976C 3D ToF imager offers a high level of functionality and maximum flexibility to optimize 3D camera designs. The sensor is ideal for applications like secure authentication for smartphones, payment terminals, smart door locks and also for virtual and augmented reality (AR/VR) headsets, service robots, and various IoT devices.”

The IRS2976C offers system VGA resolution of 640 x 480 depth points. With the world's smallest form factor of 23 mm², the imager sensor is drop-in compatible to previous IRS2877C imager and allows an easy upgrade path. The high level of integration enables a reduced bill of material (BOM), lowest form factors and simplified design. In combination with IRS9102C, Infineon’s latest VCSEL driver, the new IRS2976C allows the design of the smallest 3D camera systems at optimized costs.


Engineering samples of the IRS2976C imager are available. The new product will be presented at Mobile World Congress 2023 in Barcelona, Spain. More information is available at

Older robot vacuum cleaners used a random, inefficient, and slow cleaning pattern. Smart robots generate a map of their environment using sensors and simultaneous localization and mapping (SLAM) to localize, providing users with a floorplan from which areas can be selected for cleaning, or restricted from access. This whitepaper describes designing slimmer robots with new features using an approach with novel time-of-flight cameras.
