Deformation of stem cell nuclei by nanotopographical cues

Chalut, Kevin J.; Kulangara, Karina; Giacomelli, Michael G.; Wax, Adam; Leong, Kam (ROYAL SOC CHEMISTRY, 2010)

Cells sense cues in their surrounding microenvironment. These cues are converted into intracellular signals and transduced to the nucleus in order for the cell to respond and adapt its function. Within the nucleus, structural ...
Fiber-optic interferometric two-dimensional scattering-measurement system

Zhu, Yizheng; Giacomelli, Michael G.; Wax, Adam (OPTICAL SOC AMER, 2010)

We present a fiber-optic interferometric system for measuring depth-resolved scattering in two angular dimensions using Fourier-domain low-coherence interferometry. The system is a unique hybrid of the Michelson and Sagnac ...
Measuring morphological features using light-scattering spectroscopy and Fourier-domain low-coherence interferometry

Wax, Adam (OPTICAL SOC AMER, 2010)

We present measurements of morphological features in a thick turbid sample using light-scattering spectroscopy (LSS) and Fourier-domain low-coherence interferometry (fLCI) by processing with the dual-window (DW) method. A ...
Parallel on-axis holographic phase microscopy of biological cells and unicellular microorganism dynamics

Shaked, Natan T.; Wax, Adam (OPTICAL SOC AMER, 2010)

We apply a wide-field quantitative phase microscopy technique based on parallel two-step phase-shifting on-axis interferometry to visualize live biological cells and microorganism dynamics. The parallel on-axis holographic ...
Separating the scattering and absorption coefficients using the real and imaginary parts of the refractive index with low-coherence interferometry

Wax, Adam (OPTICAL SOC AMER, 2010)

We present an analytical method that yields the real and imaginary parts of the refractive index (RI) from low-coherence interferometry measurements, leading to the separation of the scattering and absorption coefficients ...
Simultaneous two-wavelength transmission quantitative phase microscopy with a color camera

Rinehart, Matthew T.; Shaked, Natan T.; Wax, Adam (OPTICAL SOC AMER, 2010)

We present a quantitative phase microscopy method that uses a Bayer mosaic color camera to simultaneously acquire off-axis interferograms in transmission mode at two distinct wavelengths. Wrapped phase information is ...
