Remote sensing of pressure inside deformable microchannels using light scattering in Scotch tape
Kyungduk Kim, Hyeonseung Yu, Joonyoung Koh +3
We present a simple but effective method to measure the pressure inside a deformable micro-channel using laser scattering in a translucent Scotch tape. Our idea exploits the fact t…
In vivo deep tissue imaging using wavefront shaping optical coherence tomography
Hyeonseung Yu, Jaehyun Peter Lee, KyeoReh Lee +5
Multiple light scattering in tissue limits the penetration of optical coherence tomography (OCT) imaging. Here, we present in-vivo OCT imaging of a live mouse using wavefront shapi…
Measuring large optical reflection matrices of turbid media
Hyeonseung Yu, Jung-Hoon Park, YongKeun Park
We report the measurement of a large optical reflection matrix (RM) of a highly disordered medium. Incident optical fields onto a turbid sample are controlled by a spatial light mo…
Recent advances in wavefront shaping techniques for biomedical applications
Hyeonseung Yu, Jongchan Park, KyoReh Lee +4
Due to the highly inhomogeneous distributions of refractive indexes, light propagation in complex media such as biological tissue experiences multiple light scattering events. The…
Focusing through turbid media by polarization modulation
Jongchan Park, Jung-Hoon Park, Hyeonseung Yu +1
We demonstrate that polarization modulation of an illumination beam can effectively control the spatial profile of the light transmitted through turbid media. Since the transmitted…
Optogenetic control of cell signaling pathway through scattering skull using wavefront shaping
Jonghee Yoon, Minji Lee, KyeoReh Lee +6
We introduce a non-invasive approach for optogenetic regulation in biological cells through highly scattering skull tissue using wavefront shaping. The wavefront of the incident li…
