Sony Semiconductor Solutions (SSS) has announced the upcoming release of the IMX479 stacked, direct time-of-flight (dToF) SPAD depth sensor for automotive lidar systems, delivering both high-resolution and high-speed performance.
The sensor product employs a dToF pixel unit composed of 3×3 (horizontal × vertical) SPAD pixels as a minimum element to enhance measurement accuracy using a line scan methodology. In addition, SSS’s proprietary device structure enables a frame rate of up to 20fps, which is said to be the fastest for a high-resolution SPAD depth sensor with 520 dToF pixels. e
The new product enables the high-resolution and high-speed distance measuring performance required for an automotive lidar.
