We present a 2/3-inch 2.1Mpixel 3D backside-illuminated SPAD image sensor.
Newly proposed pixel architecture based on weighted photon counting technique achieves 156dB single-shot dynamic range with LED flicker mitigation.
Read noise-free operation with seamless global shutter ensures robust image capture of distant targets under 0.1lux lighting conditions.
Intra-frame nondestructive readout enables acquisition of short exposure frames with reduced motion blur, in parallel with long exposure frame acquisition. |
