A large-area optical sensor that reports where a light spot lands, made by coating silicon with a conductive polymer in a simple low-temperature process.
Key results
Position sensitivity above 100 mV/mm.
Nonlinearity below 3% and response correlation above 0.995.
Response time under 4 ms for infrared illumination.
