Super-resolution three-dimensional fluorescence and optical diffraction tomography of live cells using structured illumination generated by a digital micromirror device
Seungwoo Shin, Doyeon Kim, Kyoohyun Kim +1
We present a multimodal approach for measuring the three-dimensional (3D) refractive index (RI) and fluorescence distributions of live cells by combining optical diffraction tomogr…
Tomographic active optical trapping of arbitrarily shaped objects by exploiting 3-D refractive index maps
Kyoohyun Kim, YongKeun Park
Optical trapping can be used to manipulate the three-dimensional (3-D) motion of spherical particles based on the simple prediction of optical forces and the responding motion of s…
The effects of spatiotemporal coherence on interferometric imaging
Seungwoo Shin, Kyoohyun Kim, KyeoReh Lee +2
Illumination coherence plays a major role in various imaging systems, from microscopy, metrology, digital holography, optical coherence tomography, to ultrasound imaging. Here, we…
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…
Single-shot optical imaging through scattering medium using digital in-line holography
Vinu R., Kyoohyun Kim, Atul S. Somkuwar +2
Non-invasive and single-shot holographic imaging through complex media is technically challenging due to random light scattering which significantly scrambles optical information.…
Optical diffraction tomography using a digital micromirror device for stable measurements of 4-D refractive index tomography of cells
