For a long time, it was thought that this [technique] required telescopes in space,” says John Mather, the Nobel ...

Abstract: This paper discusses the applicability conditions of the Physical Optics (PO) approximation and investigates its predictive power for far-field diffraction patterns of Reconfigurable ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

Flexible, and easy-to-use Python diffraction simulator that focuses on visualizing physical optics phenomena. The simulator uses mainly scalar diffraction techniques for light propagation, provides a ...

Scientists at the UK's National Physical Laboratory (NPL) have published their latest findings on laser frequency stabilization, demonstrating what they call "an unprecedented level of performance ...

Las Positas College (LPC) and Lawrence Livermore National Laboratory (LLNL) are offering a laser-optics workshop through the school’s Community Education program. The eight-week class, which begins ...

UHRL, San Jose, CA, USA. Likewise, periodic Bragg diffraction can be interpreted in more than one way to include quantization; but our dual diffraction, that is partly (linear) Bragg diffraction and ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...
