The key innovation of our propulsion concept is the unique coupling of a neutral particle beam with a laser beam, a scheme which nearly eliminates thermal expansion and diffraction during beam ...

Researchers have developed a novel, lab-tested design for a laser-driven light sail that exhibits self-stabilization capabilities. This innovative design mitigates beam misalignment, a critical ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

(Nanowerk News) Turning up the intensity of x-ray beams used to probe the atomic structures of materials can actually reduce the intensity of x-rays scattered from the material, a RIKEN-led team has ...

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for ...

Digital holography possesses the advantages of wide-field, non-contact, precise, and dynamic measurements for the complex amplitude of object waves. Today, digital holography and its derivatives have ...

Researchers in South Korea have developed an ultra-small, ultra-thin LiDAR device that splits a single laser beam into 10,000 points covering an unprecedented 180-degree field of view. It's capable of ...
