This page lists some of the notes which I have written over the course of my PhD. These works would not have been possible without my colleages in the Turbulent Combustion Lab at NTNU (Sam, José, to name a few etc). I hope that they will be useful quick-start guides for someone starting out on an experimental PHD, working on optical diagnostics and signal processing. The topics include optics, integral transforms, and acoustic waves.

Lab Safety

Safety first! As always. Many things can possibly go wrong in the laboratory. It is hoped that with these checklists, (newbie) users in the Combustion Lab of NTNU will be able to safely navigate through the many stressful experimental campaigns with all limbs and equipment intact. I have been through those moments of uncertainty and fear of making catastrophic mistakes which will disintegrate the entire lab to ashes, so I definitely get that! Nonetheless, it is part of the experience and a meaningful learning process. The first checklist is for general use, and the second is relevant if one is using ammonia gas. A big thank you to everyone in their lab for their inputs and contributions to these checklists! Definitely much appreciated.

This set of notes provides some definitions on the terms used in optics and the different lens classification. Includes a short guide on how to set up a laser sheet.
This set of notes briefly covers concepts related to acoustic waves (Helmholtz Equation), and fluid mechanics (Equations of State, Transport Theorem). Includes codes related to the implementation of the Multi-Microphone Method (MMM) for wave decomposition, and a short descrption on the numerical implementation as well. In the process of rewriting the codes (previously written in MATLAB) to python so that it is more accessible, so stay tuned!
A (very brief) set of notes concerning integral transforms (Abel, Fourier).
