Title: On-Sky Demonstration of Speckle Stabilization for SPIFS

Abstract: During this semester, we wish to perform proof of concept testing of a new observational technique called Stabilized-sPeckle Integral Field Spectroscopy (SPIFS). 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 a testbed instrument containing all the components necessary to prove the concept without the integral field unit. The 2.1 meter telescope at Kitt Peak is ideal for characterization and our proposal calls for two observing runs separated by a few weeks. On the first run, we would observe and characterize speckle patterns in real time with our camera and optics. On the second run, we would use the speckle data from the first run to condition the system response and achieve loop closure where we actually stabilize bright speckles onto a science camera.
