Super-bit-resolution enabled by noise-tolerant temporal single pixel imaging

Super-bit-resolution implies the survival of data that could have been lost beyond the digitizing bit resolution. This yet unexplored ability to beat the bit threshold of output readings has been achieved by making temporal ghost imaging (TGI) virtually noiseless. To this end, acquired immunity against self-inflicting noise was granted by implementing orthogonalized illumination in one-time readout TGI as a temporal analog of single pixel imaging. The results have greater impacts on metrology and signal processing, not limited to (T)GI.
