10kFps Image Sensor
● The invention of the optical mouse based on 2D image recognition was a big step forward for the usability of the computer mouse
● Images are taken at different times & shifts or rotations are detected
● This principle can also be used for other applications like robotics
● A robot/car is equipped with an auxillary strobe light & a special sensor which is capable of taking pictures of the ground
● A computer calculates the speed & direction of the vehicle, & can use this data in calculating position
● Electrical & optical requirements for such sensors are unique due to high speed, requiring a high frame rate
● Conventional image sensors lack sensitivity & suffers from image blur
● Designed for robotic applications to track position & speed
● 10,000 images per second for fast vehicles
● 32x32 pixel of highly linear CMOS process flow
● Low-leakage pixel with narrow wavelength sensitivity to reduce blur from IR components
● Linearity down to very low light levels
● small 1mm² image sensor area, & a low cost solution
