Digital Holographic Microscopy for Measurement of Cellular Refractive Indices
… down as it propagates through the medium. A digital holographic microscope (DHM) has been constructed to measure the refractive index of living biological cells as this information has been shown to be an indicator of cell health and is also central to cellular biomechanics measurements made …

Microalgal swimming in fluid environments: experimental and numerical investigations
… such as Particle Image Velocimetry (PIV) and Digital Holographic microscopy were employed. The two-dimensional PIV results showed that Dunaliella were influenced by the fluid flow as soon as the local (or ambient) flow velocities surrounding the cells exceeded the individual (flow subtracted) …

Mechanisms of reorientation in phytoplankton : fluid shear, surface interactions, and gravitaxis
… the solid surface. Both conventional imaging and digital holographic microscopy were used to track cells, in two and three dimensions, respectively. Results revealed that the presence of a surface can affect cell distributions many cell diameters away from that surface, with the actual distance …

Label-free Optical Approaches for the Non-invasive Assessment of Embryo Quality
… my work demonstrated the ability of digital holographic microscopy to detect spatio-temporal changes in refractive index that were associated with increased intracellular lipid abundance, in the absence of exogenous tags. This underscores the potential for refractive index measurement …
