This practical lesson is designed to develop students’ understanding of diffraction gratings and the measurement of light wavelengths. Students will investigate how red, green, and blue light are ...

Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit ...

Intraoperative imaging of slide-free specimens is crucial for oncology surgeries, allowing surgeons to quickly identify tumor margins for precise surgical guidance. While high-resolution ultraviolet ...

We find the rainbow-like iridescence in the transparent ghost catfish to be the result of the diffraction by sarcomeres in transmission, which is distinct from most of the surface reflection ...

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 ...

Imaging the polarization of light scattered from an object provides an additional degree of freedom for gaining information from a scene. Conventional polarimeters can be bulky and usually consist of ...

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 ...
