Figure 1 – (A) Experimental schematic diagram illustrating the working principle of dual-comb ghost imaging, which uses a single-core fiber and a single-pixel detector for imaging. The wavelength-division multiplexing (WDM) technology used in optical communications, combined with dual-comb interferometry and ghost imaging techniques, enables such a minimally invasive optical front end. (B) The imaging operation involves optical detection of the “bucket sum” of each comb-line power after modulation by the target object, which is essentially a hyperspectral multiply-accumulate (MAC) operation. Computational reconstruction of the target image, which is fundamentally an inverse optimization problem, is performed using a Transformer-based deep learning model. (C) One example application of this approach is neurosurgical endomicroscopy, which requires a minimally invasive optical probe.
