Generalized image deconvolution by exploiting spatially variant point spread functions
SangYun Lee, Kyeoreh Lee, Seungwoo Shin +1
An optical imaging system forms an object image by recollecting light scattered by the object. However, intact optical information of the object delivered through the imaging syste…
Time-reversing a monochromatic subwavelength optical focus by optical phase conjugation of multiply-scattered light
Jongchan Park, Chunghyun Park, KyeoReh Lee +2
Due to its time-reversal nature, optical phase conjugation generates a monochromatic light wave which retraces its propagation paths. Here, we demonstrate the regeneration of a sub…
Optical characterization of red blood cells from individuals with sickle cell trait and disease in Tanzania using quantitative phase imaging
JaeHwang Jung, Lucas E. Matemba, KyeoReh Lee +6
Sickle cell disease (SCD) is common across Sub-Saharan Africa. However, the investigation of SCD in this area has been significantly limited mainly due to the lack of research faci…
White-light Quantitative Phase Imaging Unit
YoonSeok Baek, KyeoReh Lee, Jonghee Yoon +2
We introduce the white light quantitative phase imaging unit (WQPIU) as a practical realization of quantitative phase imaging (QPI) on standard microscope platforms. The WQPIU is a…
A simple and rapid method for detecting living microorganisms in food using laser speckle decorrelation
Jonghee Yoon, KyeoReh Lee, YongKeun Park
Measuring microorganisms in food products is a critical issue for food safety and human health. Although various approaches for detecting low-levels of microorganisms in food have…
Scattering optical elements: stand-alone optical elements exploiting multiple light scattering
Jongchan Park, Joong-Yeon Cho, Chunghyun Park +4
Optical design and fabrication techniques are crucial for making optical elements. From conventional lenses to diffractive optical elements, and to recent metasurfaces, various typ…
