频率梳与深度学习结合实现快速高保真鬼成像

Ghost imaging, a technique that reframes image formation by replacing pixelated sensors with correlation measurements between structured illumination and a single-pixel detector, offers distinct advantages in low-light settings, through scattering media, and on platforms where hardware size is limited. But while, in theory, ghost imaging provides a satisfactory solution to capturing images in photon-starved or size-constrained environments, in practice, it has been of limited use. Conventional ghost imaging is fundamentally slow, because it typically uses spatial light modulators or swept-frequency lasers to generate uncorrelated, 2D illumination patterns and project them onto the target sequentially. The use of slow,...
