Experimental set-up for super-resolution optical imaging experiments (STED and mag-STED) in our Northwest Building lab.


November 2012

With a simple telescope and an optical fiber connection to our lab we can measure the solar spectrum with orders of magnitude better accuracy than it has ever been measured before. The key to this measurement is the spectrograph we have built in our lab: a fiber fed, very high resolution Fourier transform spectrograph (FTS) which is referenced to an optical frequency comb and calibrated with our astro-comb. These measurements will help us better understand the limitations of other spectrographs used in searches for planets around other stars.

Riggers lift the optical table of the Red and Blue astro-comb into its crate at the
Fred L Whipple Observatory on Mt. Hopkins to ready its return to the CfA.

David watching the sun set from the top of the island of La Palma in the Canary Islands, Spain. Visible on the right of the photo is the Italian National Telescope, the TNG, at which HARPS-N has just completed commissioning. David, Andy Szentgyorgyi, Dimitar Sasselov, and Dave Latham have come to celebrate the successful commissioning and learn about the properties of the new instrument. David is also investigating spaces in the telescope facility to house the astro-comb, as well as enjoying a beautiful sunset.
