The idea of wavefront recording and reconstruction, known today as holography, was formulated by Gabor 1. His proof-of-principle experiment was done with the light of a high pressure mercury lamp; it ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2024.230034 discusses how the synergy of traditional techniques and deep learning enables single-frame high-precision fringe pattern ...

A theoretical astrophysicist may have solved a nearly two-decade-old mystery over the origins of an unusual 'zebra' pattern seen in high-frequency radio pulses from the Crab Nebula. A theoretical ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern. LAWRENCE — A ...
