As the individual components become bigger, they become more difficult to manufacture, increasing the cost and making them more fragile (meaning unless you’ve got a particularly careful PhD student the cost of having spares also goes up). This has lead to many instruments using techniques such as image slicing to reduce the size of individual components and make the point spread function from the telescope manageable. [[BR]][[BR]]Astrophotonics is a field that aims to combat the problems of size, cost and complexity. The idea is to take devices and technologies developed for the field of photonics and make use of them in astronomy. In this talk Robert Harris will describe his past, current and future work in a subfield of astrophotonics, photonic reformatting. This is akin to image slicing, but occurs within the fibre, meaning the devices are fully integrated. He will discuss both theoretical and practical aspects of his work and draw conclusions as to where he feels the field will go next.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2017S1/2017-03-24_Reformatting.pdf Slides: English][[BR]]Questions: German, English || |
