Journal ArticleDOI
Dual-wavelength diffraction phase microscopy for simultaneous measurement of refractive index and thickness.
TL;DR: It is found that the dual-wavelength DPM (DW-DPM) provides an accurate measurement of the volume and the refractive index of a microscopy sample with good measurement stability that results from the common-path geometry.
Journal ArticleDOI
Reduced-phase dual-illumination interferometer for measuring large stepped objects.
Behnam Tayebi,Mohammad Reza Jafarfard,Farnaz Sharif,Yoon Sung Bae,Seyyed Hossein Hosseini Shokuh,Dug Young Kim +5 more
TL;DR: A reduced-phase dual-illumination interferometer (RPDII) that measures the topography of a sample with large step height variation is presented and the basic principle and the feasibility of this novel single-shot quantitative phase imaging are experimentally demonstrated.
Journal ArticleDOI
Large step-phase measurement by a reduced-phase triple-illumination interferometer.
Behnam Tayebi,Mohammad Reza Jafarfard,Farnaz Sharif,Young Sik Song,Dongsoo Har,Dug Young Kim +5 more
TL;DR: A reduced-phase triple-illumination interferometer (RPTII) is presented as a novel single-shot technique to increase the precision of dual-illumnination optical phase unwrapping techniques.
Journal ArticleDOI
Double-field-of-view, quasi-common-path interferometer using Fourier domain multiplexing.
TL;DR: A quasi-common-path interferometer with a double field of view (FOV) obtained by Fourier domain multiplexing, whereby two interferometric images corresponding to two different areas of a sample are modulated with two different spatial carrier frequencies.
Journal ArticleDOI
Optimum phase shift for quantitative phase microscopy in volume measurement
TL;DR: It is demonstrated that the error in phase volume measurement can be effectively reduced by the enhancement of the phase signal inside the bandpass region using an optimum amount of phase, which can be controlled by changing either the medium index or the wavelength of illumination.
