New i-ToF imager enables smallest 3D camera systems with improved quantum efficiency at optimized cost

Infineon Technologies 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 (more info).
