Ptychographic lensless coherent endomicroscopy through a flexible fiber bundle
Gil Weinberg, Munkyu Kang, Wonjun Choi +2
Conventional fiber-bundle-based endoscopes allow minimally invasive imaging through flexible multi-core fiber (MCF) bundles by placing a miniature lens at the distal tip and using…
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…
Near-field imaging beyond the probe aperture limit
Eunsung Seo, Young-Ho Jin, Wonjun Choi +7
Near-field scanning optical microscopy has been an indispensable tool for designing, characterizing and understanding the functionalities of diverse nanoscale photonic devices. As…
Focusing of light energy inside a scattering medium by controlling the time-gated multiple light scattering
Seungwon Jeong, Ye-Ryoung Lee, Sungsam Kang +6
The efficient delivery of light energy is a prerequisite for non-invasive imaging and stimulating of target objects embedded deep within a scattering medium. However, injected wave…
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…
