World’s first SPAD image sensor with on-chip photon processing debuts - Interesting Engineering

Automated excerpt

Edinburgh-based semiconductor company Singular Photonics has launched Litavis, a new image sensor designed to combine photon counting, timing and statistical analysis directly on a single chip. The company describes Litavis as the world’s first single-photon avalanche diode (SPAD) sensor with in-pixel processing capable of combining imaging, timing, histogramming and photon statistics on the same device. Litavis builds on that sensitivity by making the sensor software-configurable. The same hardware can be reconfigured for different imaging tasks without requiring a new sensor design. The sensor provides continuous 256 × 256-pixel photon-counting imaging under low-light conditions.
