Abstract: Free-space optical (FSO) communication technology is widely utilized in uncrewed aerial vehicle (UAV) communication because it provides larger communication bandwidth than radio frequency ...

Abstract: Stabilization of optical beams has always been a key factor affecting the performance of many optical systems. The Adaptive optics (AO) beam stabilization system requires further development ...

Introduction:Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments ...

In 1873, Ernst Abbe proposed the famous diffraction limit theory, stating that the resolution of an optical system is limited by the light wavelength ...
