Title: On-Sky Demonstration of Speckle Stabilization for SPIFS: Part II Loop Closure
Abstract:
During the 2009B semester, we wish to perform proof-of-concept
testing of a new observational technique called Stabilized-sPeckle
Integral Field Spectroscopy (SPIFS) on the KPNO 2.1-m. These
observations would follow up a speckle characterization run that will
occur in June of the 2009A semester. The 2009A run will be used to
characterize speckle patterns through our optical system and tune the
instrument so that speckle stabilization via loop closure can be
achieved during the 2009B semester. SPIFS will enable, under certain
observational conditions and constraints, low-to-modest Strehl
diffraction-limited imaging spectroscopy from large ground-based
telescopes in the optical bandpass (i.e. V, R, and I bands). SPIFS is
capable of exploring important scientific niches which are not currently
available using existing high angular resolution techniques such as
adaptive optics or speckle imaging. At the same time, the SPIFS
instrument concept is relatively straightforward and feasible using
existing, relatively-inexpensive technology. The finished instrument
will be able to achieve better than 15 mas resolution on current
telescopes. To test the technique, we have designed and fabricated a
testbed instrument containing all the components necessary to prove the
concept without the integral field unit, and have performed in-lab
speckle stabilization.
