Angularly-resolved light scattering has been proven to be an early detector of subtle changes in organelle size due to its sensitivity to scatterer size and refractive index contrast. However, for cells immersed in media with a refractive index close

We present simulated angular scattering from organelle populations of arbitrary size distribution and spatial location. Simulations will be used to explore the limitations of extracting size information from single cells, motivated by experiments.

Angle-resolved light scattering microscopy enables the size distribution of scatterers within a cell to be estimated non-invasively. Our group is working towards obtaining quantitative estimates of mean scatterer size in single cells by comparing the

Angular scattering from wavelength-scale objects can be obtained from quantitative phase images. Using Fourier phase microscopy, excellent fits with Mie theory are obtained for single micron-scale beads, and size distribution estimates are performed

The UNESCO International Day of Light, 16 May, serves to highlight the critical and diverse roles that light plays in our daily lives. Light has specific meaning to each local community, and finding that which has the greatest impact can be challengi

In this project we design and fabricate a hyperbolic metamaterials-based narrowband notch filter for the mid-wave infrared regime with an angle-of-incidence independent center-wavelength for TM polarized incident light. To achieve angle of incidence

We constructed a microscope system that obtains angular scattering information using dark-field quantitative phase imaging. In this technique, unscattered light acts as a reference for interferometry. We tested the system using polystyrene beads.

We report what is to our knowledge the first use of Fourier phase microscopy (FPM) to estimate diameters of individual single-micrometer beads and to classify cells based upon changes in scatterer size distribution. FPM, a quantitative phase imaging
