Fig. 4: Trajectory registration for moving light spot in neuro-inspired optical sensor array.
a Schematic illustration of in-sensor trajectories registration. b Predefined trace of moving targets on the sensor array. Scale bar: 200 μm. c (i) Acquired trajectory image in each step and (ii) corresponding current curves of all 100 pixels after 10 steps, (iii), (iv) Another trajectory image after erasure operation and corresponding current curves in each pixel. The velocity and light intensity of moving light spot are 40 μm s−1 and 3.1 μW μm−2, respectively.
