“…5 In the regime where the object travels within the angular ME range (C(∆x) > 0.5), S 1 and S 2 are correlated. To highlight the impact of the degree of correlation C(∆x) on the SAC, we can mathematically represent S 2 as:…”

“…Many approaches currently exist to filter out the multiply scattered light and detect only the unscattered (ballistic) or minimally scattered photons. These include methods such as time and coherence gating, which separate the ballistic photons from the scattered photons based on their transit time to the detector [2,3]; methods that rely on preserving the initial angular momentum or polarization modulation [4][5][6][7]; and methods that rely on spatial confinement, such as confocal and multi-photon microscopy [1,8]. An issue with methods that rely on detecting only the minimally scattered photons is the maximum achievable depth of penetration, since the chance of detecting a quasi-ballistic photon decreases exponentially with increasing depth.…”

“…Taken together, these observations confirm that the proposed method works extremely well, even in the presence of strong multiple-scattered waves. Experimental demonstration of CLASS microscopy with phantom samples To experimentally demonstrate CLASS microscopy, we upgraded the previous version of the CASS microscope 12 in two major respects. First, a water-dipping type objective lens (Nikon, CFIApo-40XW-NIR, 0.8 NA) with a twice larger numerical aperture than before was used for submicron resolution imaging.…”

“…Using eigenchannels to better accumulate signal waves has been attempted, but does not guarantee aberration compensation 10,11 . In our previous work, we also reported a method termed collective accumulation of single scattering (CASS) microscopy 12 , which combined both time-gated detection and spatial input-output correlation. CASS microscopy was used to preferentially accumulate single-scattered waves, which are the waves scattered only once by the target object, but not at all by the medium.…”
