Generalized reciprocal diffractive imaging for stand-alone, reference-free, fast-measurable quantitative phase microscopy
Jeonghun Oh, Herve Hugonnet, Weisun Park +1
Optical microscopy has been employed to derive salient characteristics of an object in various fields, including cell biology, flow cytometry, biopsy, and neuroscience. In particul…

Quantitative phase imaging via the holomorphic property of complex optical fields
Jeonghun Oh, Herve Hugonnet, YongKeun Park
An optical field is described by the amplitude and phase, and thus has a complex representation described in the complex plane. However, because the only thing we can measure is th…

Enhancing sensitivity in absorption spectroscopy using a scattering cavity
Jeonghun Oh, KyeoReh Lee, YongKeun Park
Absorption spectroscopy is widely used to detect samples with spectral specificity. Here, we propose and demonstrate a method for enhancing the sensitivity of absorption spectrosco…
