Forget about heavy telescopes or low magnification binoculars, these spotting scopes might be the best fit for you when ...

Compound, or catadioptric, telescopes combine lenses and mirrors for a compact option, suitable for both planetary and ...

For decades, I have been interested in the application of small-diameter aperture optics, or SDAO, to enhance visual function ...

Fiber-optic Fabry-Perot interferometers using monomode fibers are fabricated and their basic properties of finesse, polarization, and thermal response are studied. Fiber-optic Fabry-Perot ...

A wide range of geometrical deformations of fiber optic sensors (FOSs) have been explored to improve their performance. In particular, fiber optics bent into a U-shape present various advantages over ...
