Previous digital imaging technologies, such as charge coupled devices (CCD) were limited to capturing 2D images in optimal lighting conditions, requiring cooling and noisy analogue signal processing paths.
SPADs work differently: they are P-N junctions reverse bias beyond breakdown and convert light (photons) directly into digital signal due to high inherent gain without the need for any analogue signal processing.
This eliminates inefficiencies associated with converting analogue signals and results in faster, noiseless time-resolved operation with the very lowest light levels.
Simultaneously capturing depth and temporal dimensions to generate 4D images that provide deep, data-rich insights, our sensors will enable the world to extract more information from light.
