Abstract: Abstract We propose a purely automatic and accurate phase aberration compensation method in digital holographic microscopy for phase-contrast imaging of living cells. At first, a least-squares fitting procedure is implemented to correct a large proportion… read more here.

Abstract: Objective. The skull significantly aberrates ultrasound imaging pulses due to its acoustic properties and morphology. However, in addition to aberration of sound waves, the large speed of sound and density mismatch between soft tissue and… read more here.

Abstract: The morphology and dynamics of label-free tissues can be exploited by sample-induced changes in the optical field from quantitative phase imaging. Its sensitivity to subtle changes in the optical field makes the reconstructed phase susceptible… read more here.
