Tohoku University Technology: High frame rate, low depth noise ToF sensor: T22-007

・ In-pixel analog memory array and sub-frame integration ・Frame rate : -10kfps*1, Depth noise : <1.3%*2 *1 at HS mode *2 at HP mode, 0.4-4.2m

・ Recently, ToF sensors that can measure the distance from an object are attracting attention in various fields such as automobiles, robots, and sensor. ・ However, conventional ToF sensors have a issue that it is difficult to improve both characteristics because there is a trade-off between frame rate and depth noise. ・ Therefore, this work has successfully solved the above issue by with in-pixel analog memory array for each image sensor and sub-frame integration. ・ This work achieved up to 10kfps at HS mode and depth noise is less than 1.3% at HP mode(0.4-4.2 m). ・ This work shows higher characteristics than conventional ToF sensors, and therefore, it is expected to be applied to autonomous driving sensors, autonomous running robots, factory automation (FA), drones, VR/AR, etc.
