A 100dB dynamic range high-speed dual-line optical transient sensor with asynchronous readout

We present a 100dB dynamic range 2times64 pixel dual-line optical sensor with asynchronous event-based readout. Each individual pixel of the sensor operates autonomously and responds with <100mus latency to relative intensity changes. It operates largely independent of overall scene illumination, directly encodes object reflectance, and greatly reduces redundancy while preserving precise timing information. The line sensor was fabricated using a 0.35mum standard CMOS technology. Results of the measurement performance of the sensor are presented. The intended application area is precision timing measurement under variable lighting conditions
