David Buscher

Professor of Experimental Astronomy

About me

Portrait photo of me I teach physics at the University of Cambridge and I work on the design, construction and scientific exploitation of high-resolution and high-precision astronomical instruments.

I lead the Precision Instrumentation activity in the Cavendish Astrophysics group and am the principal designer of the Magdalena Ridge Observatory Interferometer, an imaging interferometer under construction in New Mexico.


More details on the EPSRC grant now on this page
I have been awarded (along with Chris Haniff and John Young) a £900k EPSRC grant entitled "Machining metre-sized gratings with nanometre accuracy". This extends the technology we developed for delay lines in long-baseline optical interferometers to the application of manufacturing the very large gratings needed for high-resolution spectroscopy on the next generation of Extremely Large Telescopes (ELTs). The ultimate aim is to extend this to arbitrary patterning of 2-dimensional surfaces for ultra-precision manufacturing.
I have been elected as President of the Scientific Council of the European Interferometry Initiative (EII), along with Claudia Paladini (Vice-President) and Karine Perraut (Secretary).

"... this benefits not only from Buscher's technical expertise but also from his years of teaching. Practical Optical Interferometry is a wonderful resource that fulfills a long-standing need for advanced undergraduates, graduate students, and postdocs enticed by the prospects of sub-milliarcsecond spatial resolution."
