How to align a 4F optical system for digital inline holographic microscopy.

How to align a 4F optical system for digital inline  holographic microscopy. Uncategorized

The goal of a 4F system in holography is to generate a collimated beam of single-wavelength light, shine it through a sample, and then magnify and refocus this light onto a camera sensor. When the collimated light hits the sample, it creates concentric rings around the objects known as diffraction patterns or Airy discs, like this: These diffraction patterns provide […]

IEC Reactor Update Fusion

After a bit of a hiatus, we’re making good progress on the reactor! We recently replaced the cathode and feedthrough with a titanium surgical rod and a titanium bicycle stem spacer. Alumina tubing at this size is extraordinarily expensive, so we repurposed TIG welding nozzles for the shielding. I’m quite impressed with the results, but the new materials have added […]

How to install Ubuntu Linux and run Jupyter Notebook on Windows 11 (with CUDA!)

How to install Ubuntu Linux and run Jupyter Notebook on Windows 11 (with CUDA!) Coding

Dual-booting Windows 10/11 and Ubuntu is still the preferred method for power users, but for regular folk like me I think using the new WSL (Windows Subsystem for Linux) is totally serviceable. It makes it so much easier to multi-task since you can operate within both ecosystems at the same time. I tried a number of different methods to get […]
