Understanding optical resolution is key in microscopy, highlighting the diffraction limit and innovations in super-resolution ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

I’ve got some bad news for you: Our eyes are not always reliable sources of information. If you’ve ever stepped back from a completed project and wondered why it doesn’t look right, it’s probably ...

Abstract: Physical effects that lead to zero shift of a laser gyro (LG) are considered. It is shown that under severe thermal and mechanical deformations, the main source of zero shift is the effect ...
