Gaussian beam migration (GBM) is an advanced seismic imaging technique that utilises the propagation characteristics of Gaussian-shaped beams to construct detailed subsurface images. This method ...

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

PowerPhotonic, a developer of freeform, wafer-scale optics, this week launched a new Variable Beam Shaper, while exhibiting at SPIE Sensors and Imaging exhibition and conference, in Edinburgh, UK. The ...

It is expected that Bessel-Gaussian beams will be widely used in laser radar, and laser sensing. The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied ...
