Investigation of depth-resolved nanoscale structural changes in regulated cell proliferation and chromatin decondensation
Uttam, Shikhar; Bista, Rajan K.; Staton, Kevin; Alexandrov, Sergey; Choi, Serah; Bakkenist, Christopher J.; Hartman, Douglas J.; Brand, Randall E.; Liu, Yang (2013)We present depth-resolved spatial-domain low-coherence quantitative phase microscopy, a simple approach that utilizes coherence gating to construct a depth-resolved structural feature vector quantifying sub-resolution axial ... -
Real-time quantitative visualization of 3D structural information
Alexandrov, Sergey; Uttam, Shikhar; Bista, Rajan K.; Zhao, Chengquan; Liu, Yang (Optica, 2012)We demonstrate a novel approach for the real time visualization and quantification of the 3D spatial frequencies in an image domain. Our approach is based on the spectral encoding of spatial frequency principle and permits ... -
Spectral encoding of spatial frequency approach for characterization of nanoscale structures
Alexandrov, Sergey; Uttam, Shikhar; Bista, Rajan K.; Staton, Kevin; Liu, Yang (American Institute of Physics, 2012-07-17)An approach to acquire axial structural information at nanoscale is demonstrated. It is based on spectral encoding of spatial frequency principle to reconstruct the structural information about the axial profile of the ...
