Phase-contrast microscopy converts the phase shift of light passing through a transparent
specimen, eg, a biological cell, into brightness variations in an image. This ability to observe …

Quantitative phase microscopy (QPM), a technique combining phase imaging and
microscopy, enables visualization of the 3D topography in reflective samples, as well as the …

High-throughput quantitative phase imaging (QPI) is essential to cellular phenotypes
characterization as it allows high-content cell analysis and avoids adverse effects of staining …

Diagnosis of malaria is important for its medication and treatment. An automatic compact
diagnostic tool will be advantageous especially for healthcare personnel working in …

We show that phase objects may be computed accurately from a single color image in a
brightfield microscope, with no hardware modification. Our technique uses the chromatic …

We demonstrate lensless quantitative phase microscopy and diffraction tomography based
on a compact on-chip platform, using only a CMOS image sensor and a programmable color …

Digital holographic microscopy (DHM) allows optical-path-difference (OPD) measurements
with nanometric accuracy. OPD induced by transparent cells depends on both the refractive …

Aberrations and the distortions due to the imaging optics can be compensated in
quantitative phase microscopy of thin phase objects by digital holography using a single …

Regulated cell death modalities such as apoptosis and necroptosis play an important role in
regulating different cellular processes. Currently, regulated cell death is identified using the …

We present a phase-shifting interferometric technique for imaging live biological cells in
growth media, while optimizing spatial resolution and enabling potential real-time …
