White paper: SPAD vs sCMOS

One of the main challenges in single-photon camera development is the search for the best trade-off between the sensitivity of the camera, and its noise. This signal-to-noise ratio (SNR) is a critical metric in imaging: high SNR indicates that the signal of interest is strong relative to the noise, resulting in clear and accurate image representation.

The goal of this paper is to demonstrate the capabilities of our SPAD512² camera in low light-conditions, and to compare its SNR to a scientific CMOS camera. We show and explain why SPADs get better SNR values under low-light conditions, making our SPAD512² camera excel in applications like biomedical imaging, quantum computing, or surveillance in dimly lit environments.
