Hi all, Some of us might be on another continent but the instrumentation meeting powers through. Send your slides to m.darcis(a)sron.nl and haffert(a)strw.leidenuniv.nl and I hope to see you in the Oort room at 11:00.

Hi all, For those attending our pool outing tomorrow, I booked three pool tables at pool cafe the church (https://poolcafethechurch.nl/) at 19:30 for an hour. In case people also want to have diner before we can meet let’s say at 17:30 at the bike parking and find something together. Looking forward to seeing you there. Cheers, Michiel

Hi all, Although carnival season has officially started, it is time for another instrumentation meeting. This week we again see each other in the Oort room for another famous slide roulette. So for those without a PhD yet send in your two slides with plots/images of what you are currently working on or have been doing the previous week to haffert(a)strw.leidenuniv.nl and m.darcis(a)sron.nl. For the folks online:

Hi all, We have been blessed with presentations lately, but this week is a classic instrumentation meeting with slides, slides, and you guessed it, slides. Therefore, send in your two slides to haffert(a)strw.leidenuniv.nl and m.darcis(a)sron.nl and I will see you at 11 in the Oort room. Cheers, Michiel

Hi all, This week is another presentation. Willem Jellema from SRON Groningen will join us and give a talk about Far-IR Linear Variable Filter technology for PRIMA’s hyperspectral imager. After that we will continue with our usual slide roulette so send your slides to m.darcis(a)sron.nl and haffert(a)strw.leidenuniv.nl. See you there.

Hi all, This week we have our own Emily van Hese who will give us the privilege of seeing her presentation that she will give during the ICSOS conference in Kyoto. The abstract reads as follows: 'Enabling optical satellite-to-ground (quantum) communication links necessitates reducing the free-space to fibre coupling losses induced by atmospheric turbulence. Adaptive optics (AO) and multi-mode fibres (MMF) are two of the most prominent methods to achieve a limited fibre coupling loss. AO is a mature technology and is already used to great effect. Meanwhile multi-mode fibres promise similar performance, while boasting entirely passive systems. However, the necessary high-order systems of either technology may lead to high complexity solutions and high costs. A hybrid solution featuring low-order systems of both technologies might offer the required performance while circumventing the need for high-order systems. This paper studies the optimal combination of AO and MMF by identifying trade-offs between them and investigating the relative merits of potential individual and combined systems for an LEO satellite optical downlink using numerical simulations. For each simulated MMF size, the minimum required level of adaptive optics correction for a median coupling losses of 2 dB is evaluated.' After her presentation we will continue with our usual slides game. Therefore send your slides to m.darcis(a)sron.nl<mailto:m.darcis@sron.nl> and haffert(a)strw.leidenuniv.nl<mailto:haffert@strw.leidenuniv.nl>.
