 We are in the Optics Lab of the Advanced Instrumentation and Technology Centre and this is where I work. We are assembling adaptive optics systems with artificial stars for astronomy and space applications. I'm Noelia Martinez and I am a postdoctoral researcher here at the Austrian National University. This lab is mostly used for integration of big things as you can tell by the amount of big optics that we have on the optical benches. So my current research project focuses on correcting for the atmospheric effect on the light and for that we use adaptive optics systems that need a reference source on the sky that could be a natural star or an artificial star that we create ourselves with lasers. So to create our artificial stars we need an optical system that will propagate our guide-style laser from the laser head all the way outside of the telescope. So our optical system needs to be aligned with very tight tolerances to keep the quality of our artificial star. So that's why we use things like this, like this interferometer to measure how well our optical system is. I love working in the lab I think in all senses. I actually love the whole process from like the design bit to the actual experimentation. I'm definitely a hands-on person. When I tell people that I'm working here creating artificial stars on the sky I pretty much get always the same type of reaction, it's like a big whoa, that sounds very cool.
