Samsung unveils new Time-of-Flight (ToF) sensor for phones

Samsung just unveiled its latest Time-of-Flight (ToF) sensor, the ISOCELL Vizion 33D.

The South Korean company claims its ISOCELL Vizion 33D ToF sensor can take precise depth measurement of fast-moving objects due to the 4-tap demodulation system and 120fps support. Each pixel can receive four phase signals at the same time (0°, 90°, 180°, and 270°) to generate a depth image with just a single frame.

The high-resolution VGA ToF sensor can detect the depth of an object within up to 5m with high accuracy. The ISOCELL's pixel technology and high resolution allow the Vizion 33D to accurately separate objects from the background with 3D bokeh effect. 

The Deep Trench Isolation Technology (DTI) helps to maximise isolation betwee pixels to reduce crosstalk, while Backside Scattering Technology (BST) improves the sensor's quantum efficiency.

Another key feature of ISOCELL Vizion 33D is its power efficiency; it is stated to have a total power consumption of under 400mW for both IR illuminator and the ToF sensor, which makes it possible for users to enjoy AR games and video bokeh all day.

Possible applications of the ISOCELL Vizion 33D include accurate and quick autofocus, facial authentication for mobile payment services, pro-grade shots with bokeh effects, and creation of accurate 3D object images.
