Digital holographic microscopy (DHM) is a well-known microscopy technique using an interferometric architecture for quantitative phase imaging (QPI) and it has been already implemented utilizing a ...

Scatterometry is an optical metrology technique in which light scattered from a specifically designed grating stack (overlay target) is measured in the far-field. Using 1D periodic overlay target ...

Here, we reported an ingenious fabrication of moisture responsive graphene-based actuator via unilateral two-beam laser interference (TBLI) treatment of graphene oxide (GO) papers. TBLI technique has ...

Structured illumination microscopy (SIM) is a superresolution technique that illuminates the specimen with a sine-modulated pattern. The frequency of the illumination pattern, i.e., the inverse of the ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 10 years old. A couple of weeks ago, I listed ...

We prove theoretically and experimentally the concept of polarization holography by producing visible diffraction through radiation emitted by plasmonic nanoantennas. We show a methodology to ...

Previous implementations of structured-illumination microscopy (SIM) were slow or designed for one-color excitation, sacrificing two unique and extremely beneficial aspects of light microscopy: ...
