Optical interferometry is a powerful tool for measuring and characterizing areal surface
topography in precision manufacturing. A variety of instruments based on optical …

Far field optical nanoscopy has been brought to the forefront with the 2014 Nobel Prize for
chemistry in fluorescent nanoscopy for revealing intra-cellular details of tens of nm. In this …

Here, we designed and prepared a series of hyperbranched porous polymers constructed
using fluorene branches and pyrene core, and all hyperbranched porous polymers exhibit …

We demonstrate the influence of edge effects on the photothermal-induced phase shift
measured by a homodyne quadrature laser interferometer and compare the experiments …

The traditional optical detection method has a limitation in detecting closed cracks in optical
elements. In this Letter, a novel, to the best of our knowledge, method has been developed …

Full-field optical coherence tomography (FF-OCT) is a widely used technique for
applications such as biological imaging, optical metrology, and materials characterization …

By applying the proposed high-dynamic-range (HDR) technique based on exposure
bracketing, we demonstrate a meaningful reduction in the spatial noise in image frames …

Differential interferometry is an effective method that has high contrast and can effectively
overcome the “duplicate image” problem caused by shear interferometry. However …

A route of spatial modulation-assisted scanning white-light interferometry with the inhibition
of background noises and light source fluctuations for the topography measurement of micro …

Characterizing very small particles, from a few dozen micrometers to the nanometric scale, is
a very challenging application in a wide range of domains. In this work, we demonstrate …
