Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...

High-precision alignment between the microlens array and the fiber-positioning microplate is of great significance in developing fiber-based integrated field units (IFU). In this paper, we propose a ...

A laser beam is shone onto a variable rectangular aperture. The size of the hole determines the type of diffraction produces on the screen. Very small apertures produce Fraunhofer diffraction, and ...

A laser beam is shone onto a ball bearing and a bright spot appears at the centre of the object’s shadow due to Fresnel diffraction. Place the laser on top of the lab jacks, making sure the laser is ...

NASA has proposed shooting at the moon to further our understanding of what it's made of. The out-of-this-world plan would involve an astronaut or rover using a special gun to shoot sensors into the ...
