This review gathers together 15 special topics in modern interferometric metrology
representing a sampling of historical, current and future developments. The selected topics …

Neurons undergo nanometer-scale deformations during action potentials, and the
underlying mechanism has been actively debated for decades. Previous observations were …

The surface texture is functionally important. It can be characterised using a set of
parameters. The errors in determining the parameters should be small. In this paper, areal …

Label-free optical imaging is valuable in biology and medicine because of its non-
destructive nature. Quantitative phase imaging (QPI) and molecular vibrational imaging …
