Phase from Defocused Color Images

We introduce a method for recovering-phase information inspired by transport of intensity (TIE). Instead of images at multiple planes, we use defocused images at a single plane with multiple wavelengths, obtained using standard Bayer filters.

Quasi Light Fields: A Model of Coherent Image Formation

We develop a model of coherent image formation that strikes a balance between the simplicity of the light field and the comprehensive predictive power of Maxwell's equations, by extending the light field to coherent radiation.

Wigner Analysis of 3-D Coherence Imaging

We interpret 3-D coherence imaging with Wigner analysis. The mutual intensity and the Wigner distribution function are associated with the Fourier slice theorem, where the 3-D manifold of 4-D space is sufficient for 3-D imaging.

Bubble Size Measurement in High-Density Air-Water Mixture Flows with Wide Size Distributions Using Digital Holography

We present experimental results of using in-line digital holography to measure bubble sizes in high-density air-water mixture flows with a wide size distribution.
