Back-illuminated
ToF Image Sensor
Sony announced the release of a back-illuminated, time-of-flight (ToF) image sensor which is 1/2-type, VGA resolution and delivers improved depth sensing performance. The new sensor is part of the DepthSense lineup, a group of depth-sensing image sensor products with range finding capability.
The small size of the image sensor was achieved thanks to its 10µm square pixel. It is possible to capture high-precision depth maps in a VGA resolution at close distances of approximately 30cm to 1m. Because the sensor captures depth maps for each frame, it enables image capture at a higher frame rate than when using a laser to scan the object for distance measurement.
