Canon's 3.2 MP SPAD Camera: Specifications

Canon's 3.2 MP SPAD camera has received some press coverage:

PetaPixel: https://petapixel.com/2023/04/03/canons-new-sensor-enables-long-range-night-vision-capabilities/

YMCinema: https://ymcinema.com/2023/04/03/canon-develops-interchangeable-lens-camera-that-sees-in-the-dark/ 

Unfortunately I have not been able to find a spec sheet. The next best thing for now is to see the 2021 IEDM proceedings paper titled "3.2 Megapixel 3D-Stacked Charge Focusing SPAD for Low-Light Imaging and Depth Sensing" (Morimoto et al., Canon Inc., Japan).  Thanks to Prof. Eric Fossum for pointing this out in a comment on an earlier post!

Abstract:
We present a new generation of scalable photon counting image sensors, featuring zero read noise and 100ps temporal resolution. Newly proposed charge focusing single-photon avalanche diode (SPAD) is employed to resolve critical trade-offs in conventional SPAD pixels. A prototype 3.2 megapixel 3D-stacked backside-illuminated (BSI) image sensor with 1-inch format demonstrates the best-in-class photon detection efficiency (PDE), dark count rate (DCR) and timing jitter performance with the largest array size ever reported in avalanche photodiode (APD)-based image sensors. The proposed technology paves the way to compact and high-definition photon counting image sensors for low-light imaging and 3D time-of-flight sensing.
