Abstract: Lateral shearing interferometry is an effective method for directly measuring the depth gradient of aspherical surfaces. To address the low phase reconstruction accuracy resulting from the ...

The research team’s semi-transparent solar concentrator can be directly coated onto standard window glass. It uses liquid crystal films to reflect and guide circularly-polarized sunlight to solar ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

Scientists have created a transparent solar coating that turns ordinary windows into clean energy generators without affecting clarity. Using cholesteric liquid crystal layers, the coating redirects ...

Since its inception, augmented reality (AR) technology has faced a persistent engineering challenge: achieving a wide field of view (FOV) and excellent display quality within a compact and lightweight ...

As the frontrunner of QuantLase Lab, Dr. Pramod Kumar explores how advanced quantum optics and photonic intelligence are shaping the future of sustainable computation. The world is increasingly ...

Diffractive diffusers and beamsplitters for high-power laser applications — in stock and ready to ship. HOLO/OR Diffractive Diffusers precisely convert collimated beams into square or circular ...

A team of scientists is developing a "quantum-sensitive" device that could capture direct images of Earth-like exoplanets — something astronomers tend to consider so difficult it's nearly impossible.
