Imaging through random media using coherent averaging
Byungjae Hwang, Taeseong Woo, Cheolwoo Ahn +1
We propose and demonstrate a new phase retrieval method for imaging through random media. Although methods to recover the Fourier amplitude through random distortions are well esta…
One-wave optical phase conjugation mirror by actively coupling arbitrary light fields into a single-mode reflector
KyeoReh Lee, Junsung Lee, Jung-Hoon Park +2
Rewinding the arrow of time via phase conjugation is an intriguing phenomena made possible by the wave property of light. To exploit this phenomenon, diverse research fields have p…
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…
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…
