The analytical modelling of the diffraction pattern produced by a laser pulse passing through a circular aperture, as shown in Fig. 1, was performed using Hertz vector diffraction theory (HVDT).

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230039 discusses diffraction-limited visible imaging for large aperture telescopes.

Place the aperture on the optical rail. Plug in the laser and aim it at the slit. Adjust the size of the aperture such that the Fraunhofer diffraction pattern is visible. Use the lab jacks to elevate ...

The Laowa 8-15mm f/2.8 FF Zoom Fisheye covers all the bases for various full-frame mirrorless cameras, working as both a ...
