Samsung New ISOCELL Vizion Sensors for Robotics and XR

Two new ISOCELL Vizion sensors the global shutter sensor, the ISOCELL Vizion 931, and the time-of-flight (ToF) sensor, the ISOCELL Vizion 63D were unveiled today by Samsung Electronics, a global pioneer in innovative semiconductor technology. Samsung’s ISOCELL Vizion family, which was first unveiled in 2020, consists of ToF and global shutter sensors made expressly to provide visual capabilities for a wide range of next-generation mobile, commercial, and industrial use cases.

Haechang Lee, Executive Vice President of Samsung Electronics‘ Next Generation Sensor Development Team, stated, “With their cutting-edge sensor technologies, Samsung’s ISOCELL Vizion 63D and ISOCELL Vizion 931 will be essential in facilitating machine vision for future high-tech applications like robotics and extended reality (XR).” Utilizing their extensive background in technological innovation, they are dedicated to propelling the swiftly growing image sensor industry forward.

ToF sensors estimate depth and distance by timing the duration of light emission from an item to its location, much like bats do with echolocation.

In particular, Samsung’s ISOCELL Vizion 63D is an indirect ToF (iToF) sensor that senses its environment in three dimensions by measuring the phase difference between emitted and reflected light. The Vizion 63D is perfect for high-resolution and accurate depth measuring applications such as facial verification, XR devices, and industrial and service robots. Its remarkable accuracy and clarity make it an excellent choice.

The first iToF sensor in the market with an integrated depth-sensing hardware image signal processor (ISP) is the ISOCELL Vizion 63D. It can accurately record 3D depth information without the assistance of a second chip thanks to its novel one-chip design, which allows for a 40% decrease in system power consumption over the previous ISOCELL Vizion 33D product. Additionally, the sensor can process images at up to 60 frames per second at QVGA resolution (320 x 240), an extremely popular display resolution in the business and industrial sectors.

The ISOCELL Vizion 63D obtains high Video Graphics Array (VGA) resolution (640×480) within a 1/6.4″ optical format, which makes it a perfect fit for small, portable devices. It is based on the industry’s smallest 3.5 pixel size in iToF sensors.

The Vizion 63D sensor has the highest degree of quantum efficiency in the industry, reaching 38% at an infrared light wavelength of 940 nanometers (nm), thanks to backside scattering technology (BST), which improves light absorption. This makes it possible to have less noise and more light sensitivity, which leads to sharper images with less motion blur.

Additionally, the ISOCELL Vizion 63D’s measurable distance range has been greatly increased from five meters to ten thanks to the support for both flood (high-resolution at short range) and spot (long-range) lighting modes.

Optimized to Capture Dynamic Movements Without Distortion: ISOCELL Vizion 931

A global shutter image sensor designed to capture fast motions without the “jello effect” is the ISOCELL Vizion 931. Global shutter sensors, which mimic human vision, capture the entire image at once or “globally,” in contrast to rolling shutter sensors, which scan the scene line by line from top to bottom in a “rolling” motion. Due to its ability to capture clear, distorted images of moving objects, the ISOCELL Vizion 931 is a great choice for motion-tracking applications in XR gadgets, gaming systems, robotic service and logistics, and drones.

With its one-to-one ratio VGA resolution (640 x 640) design, the ISOCELL Vizion 931 is the best option for iris identification, eye tracking, and facial and gesture detection in head-mounted display devices like XR headsets because it fits more pixels into a smaller form factor.

In addition, the ISOCELL Vizion 931 delivers an astounding 60% quantum efficiency at 850nm infrared light wavelength the highest level in the industry. This achievement was made feasible by combining the BST technique employed in the ISOCELL Vizion 63D with Front Deep Trench Isolation (FDTI), which inserts an insulating layer between pixels to increase light absorption.

With the help of multi-drop, which the Vizion 931 offers, up to four cameras may be easily connected to the application processor with just one wire. The sensor gives gadget manufacturers more design options because it requires less wire.

Sensors from Samsung, the ISOCELL Vizion 63D and ISOCELL Vizion 931, are now being sampled by OEMs overseas.
