Powerful 3D depth sensing for every product

We at pmd develop cutting edge 3D image sensors and 3D cameras based on the Time-of-Flight (ToF) principle. A Time-of-Flight camera can see depth by measuring the distance to every single projected pixel in a scene. With this technology, we help intelligent products in nearly every industry to see, understand and recognize the world. Our versatile 3D cameras bring FaceID and image beautification to smartphones, gesture control and driver monitoring to cars, environmental mapping to augmented reality headsets and autonomous navigation to robots and drones.

pmd - the leading 3D ToF technology provider

pmd is the world's leading supplier of 3D imaging technologies based on the Time-of-Flight principle. In addition to our headquarters in Siegen/Germany and our other offices in Germany, we have additional offices in San Jose/USA, Shanghai/China, and Seoul/Korea. Our customers from the consumer, automotive, industrial automation, and robotics industries trust our reliable camera reference designs and powerful as well as robust image sensors for real-time 3D distance perception. Agile, dynamic product teams embody our customer first focus.

All this adds up to pmd’s proven optimization for mass-market production and shows the adaptability and reliability of our 3D ToF technology.

Impressive!

What is Time-of-Flight?

Our 3D cameras use a technology called Time-oF-Flight, well known in technical implementations like radars, but also in nature – e.g. bats use the same principal with ultrasound waves to navigate during nighttime. In our case, to detect the absolute 3D distance of a scenery, the camera is transmitting an intensity modulated flash light signal. Due to the time, it takes the light to travel to the object and back there is in each pixel a timing offset between the transmitted and received lightwave. This offset depends on the distance of the object, which is observed by the pixel and can be easily calculated. Our Time-of-Flight cameras work well in complete darkness and with our patented SBI technology even robust in direct sunlight.

From Pixel to Final Product

The 3D PMD Pixel

Everything starts with the pmd pixel. Based on the PMD principle – which we have invented – our pixel detects intensity and distance values with high accuracy in parallel. By continually advancing the pixel design, we were able to increase its performance dramatically. With our new 7µm pmd pixel, we enable smaller sensors with a higher resolution. Despite its small size, every pixel has our patented sunlight suppression directly integrated to deliver superior robustness against other light sources, such as sunlight or other IR emitting light sources.

  1. New 7µm Pixel
  2. Patented Suppression of Sunlight (SBI) in every Pixel
  3. Highly Sensitive to 940nm Infrared Light

The new REAL3™ ToF Sensor

Together with our partner Infineon, we jointly develop and build the CMOS 3D image sensor based on our unique pmd pixel matrix. Infineon contributes all functional blocks for the system-on-chip (SoC) integration and together we developed the pmd ToF optimized CMOS manufacturing process. As one of the biggest semiconductor manufacturers worldwide, Infineon shipped millions of 3D image sensors and counting.
The latest generation REAL3™ ToF image sensor IRS2771C is especially designed to meet the requirements of the mobile consumer device market. With 150k 3D Pixels (HVGA) the sensor has a resolution four times higher than most ToF solutions on the market today. Its robustness against ambient light and its energy efficiency make this imager unparalleled in the market. Samples are available in March 2019, mass production starts in Q4 2019.

  1. HVGA Resolution (448 x 336)
  2. 4th Generation REAL3™ Depth-Sensor
  3. Only 4.6 x 5mm Small

The new LG G8 ThinQ with Front-Facing ToF Camera

The LG G8ThinQ is the first smartphone with a dedicated user-facing Time-of-flight (ToF) camera to enter the mass market. Highly secure authentication for both unlocking the phone and for confirming payments is enabled by the REAL3™ image sensor chip from Infineon and pmd.
In addition to that, the LG G8ThinQ can recognize a user’s unique pattern of palm veins, adding speed and convenience to unlocking the phone. This so-called Multi-Recognition reduces the ability of a hacker to build a spoofing artifact to mimic the user’s physical attribute. On top of this, the Live Bokeh function of the G8ThinQ enables aesthetic adjustments in real-time even while taking videos – and not only in post-photography. The user can also interact with the smartphone in the third dimension “beyond touch”by giving commands using hand gestures thanks to the “Air Motion” feature.
