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 ...

However, they almost all use a type of spectroscopy known as Fraunhofer diffraction. Drs. Choi and Moses decided to use a ...

Recent research has focused on various types of DOEs, including Fresnel lenses, diffraction gratings, and specialized designs like the lobster eye telescope, which are tailored for specific ...
