The results from the 2026 eclipse as seen from a little field near Morat in Switzerland....
This last year of 2024 was definitely the year of the auroras in Europe and especially in low latitudes such as France and Switzerland. With several nights where the sky turned red, a lot of people were lucky enough to see the phenomenon and photograph it. As you might now, I like the sky and I like photographing stuff in the sky. And yet I missed all those events, always with the same fashion. I ...
I have been following this new stargazer comet since the end of September. It was kind of a gamble to know if this comet would survive passing so close to the sun and survive. But thankfully, it did survive and what a spectacle it is giving us. It might not be as bright as Neowise in 2020, but this time, I have a better camera to capture it and the pictures are just amazing. Too bad the weather wa...
This year at the AKL Conference was prominently marked by discussions on Artificial Intelligence (AI). The rapid advancements in AI, significantly propelled by platforms like OpenAI and ChatGPT, have captured the attention of key decision-makers in leading companies such as Trumpf and Coherent. The plenary talk particularly emphasized the potential applications, implications, and the urgent need f...
This post aims to provide comprehensive guidance on cleaning optical elements. While there is a wealth of information available online, particularly on suppliers' websites, I want to consolidate all the knowledge I've acquired over the years working with lasers, fiber optics, and other optical equipment, including some tips and tricks....
I have started a project that requires the use of a raytracer. Basically, I hope to make a library for rendering optical paths using raytracing and simulate the result that one would get by looking through the optical system. Hopefully, I would like to be able to write somewhere that I will have a couple of lenses here and there, give the parameters such as the refractive index and curvatures and ...
So, 5 months ago, I have written a post about Artificial Intelligence and General Artificial Intelligence. You can see the tone from my first post was very optimistic, a little too much maybe, with the hope that things would accelerate soon. I have been using AI a lot recently and I want to report on my understanding of what AI can and can't do and how to use it as effectively as possible....
Continuing my series of post covering my talk from last Christmas about the use of lasers in space and astronomy. The topic today is adaptative optics. I'll explain the reason why we need it, and how it works in simple terms. Enjoy....
