Synthetic aperture phase imaging of second harmonic generation field with computational adaptive optics
Jungho Moon, Sungsam Kang, Jin Hee Hong +2
Second-harmonic generation (SHG) microscopy provides label-free imaging of biological tissues with unique contrast mechanisms, but its resolution is limited by the diffraction limi…
Tracing multiple scattering trajectories for deep optical imaging in scattering media
Sungsam Kang, Yongwoo Kwon, Hojun Lee +4
Multiple light scattering hampers imaging objects in complex scattering media. Approaches used in real practices mainly aim to filter out multiple scattering obscuring the ballisti…
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…
Wave propagation dynamics inside a complex scattering medium by the temporal control of backscattered waves
Ye-Ryoung Lee, Wonjun Choi, Seungwon Jeong +3
Shaping the wavefront of an incident wave to a complex scattering medium has demonstrated interesting possibilities, such as sub-diffraction wave focusing and enhancing light energ…
Roadmap on Wavefront Shaping and deep imaging in complex media
Sylvain Gigan, Ori Katz, Hilton B. de Aguiar +42
The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow to understand and control light propaga…
High-throughput volumetric adaptive optical imaging using compressed time-reversal matrix
Hojun Lee, Seokchan Yoon, Pascal Loohuis +3
Deep-tissue optical imaging suffers from the reduction of resolving power due to tissue-induced optical aberrations and multiple scattering noise. Reflection matrix approaches reco…
Microscopic imaging of non-repetitive dynamic scenes at 5 THz frame rates by time and spatial frequency multiplexing
Jungho Moon, Seok-Chan Yoon, Yong-sik Lim +1
Femtosecond-scale ultrafast imaging is an essential tool for visualizing ultrafast dynamics in molecular biology, physical chemistry, atomic physics, and fluid dynamics. Pump-probe…
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…
Simultaneous suppression of scattering and aberration for ultra-high resolution imaging deep within scattering media
Sungsam Kang, Seungwon Jeong, Pilsung Kang +4
Thick biological tissues give rise to not only the scattering of incoming light waves, but also aberrations of the remaining unscattered waves. Due to the inability of existing opt…
Holistic random encoding for imaging through multimode fibers
Hwanchol Jang, Changhyeong Yoon, Euiheon Chung +2
The input numerical aperture (NA) of multimode fiber (MMF) can be effectively increased by placing turbid media at the input end of the MMF. This provides the potential for high-re…
Pixelation-free and real-time endoscopic imaging through a fiber bundle
Donggyu Kim, Jungho Moon, Moonseok Kim +4
Endoscopy has been an indispensible tool in medical diagnostics, and yet the demands for reduced unit diameter and enhanced spatial resolution have steadily been growing for the ac…
Enrichment of deeply penetrating waves in disordered media
Wonjun Choi, Moonseok Kim, Donggyu Kim +4
Waves incident to a highly scattering medium are incapable of penetrating deep into the medium due to the diffusion process induced by multiple scattering. This poses a fundamental…
Exploring anti-reflection modes in disordered media
Moonseok Kim, Wonjun Choi, Changhyeong Yoon +5
Sensing and manipulating targets hidden under scattering media are universal problems that take place in applications ranging from deep-tissue optical imaging to laser surgery. A m…
