All-optical in vivo photoacoustic tomography by adaptive multilayer temporal backpropagation
Taeil Yoon, Hakseok Ko, Jeongmyo Im +3
Photoacoustic tomography (PAT) offers high optical contrast with acoustic imaging depth, making it essential for biomedical applications. While many all-optical systems have been d…

Acousto-optic volumetric gating for reflection-mode deep optical imaging within a scattering medium
Hakseok Ko, Junghoon Kim, Jin-Hee Hong +4
The imaging depth of deep-tissue optical microscopy is governed by the performance of the gating operation that suppresses the multiply scattered waves obscuring the ballistic wave…

Coherent space-gated microscopy: a step towards deep-tissue phase imaging of biological cells
Mooseok Jang, Hakseok Ko, Won Kyu Lee +2
High-resolution optical microscopy suffers from a low contrast in scattering media where a multiply scattered wave obscures a ballistic wave used for image formation. To extend the…
