High-fidelity single-pixel imaging through scattering media using quantum-state encoded illumination

Imaging through scattering media remains a challenge due to the loss of light intensity and phase, leading to poorly reconstructed images with high noise and low resolution. Here, we demonstrate a new approach, to the best of our knowledge, to image through scattering media with unprecedented grayscale accuracy by encoding quantum states within illumination patterns. The orthogonality of quantum states significantly reduces cross-pixel interference, increases grayscale accuracy, and simplifies image reconstruction. We achieve a spatial density of 180 dots per inch with excellent grayscale linearity. Our method employs a single photodetector and a consumer-grade LED projector, enabling low-cost, noninvasive imaging through scattering media.
