Abstract

Frodo is a new Differential Image Motion Monitor (DIMM) developed as a companion instrument to the Starfire Atmospheric Monitor (SAM). SAM is a Shack-Hartmann sensor that observes bright stars to provide atmospheric information above the Air Force Research Laboratory’s Starfire Optical Range (SOR). Frodo is designed to extend atmospheric characterization at the SOR into the day, estimating all of the atmospheric parameters that SAM currently provides. The optical train of Frodo has been reproduced on the Multiconjugate Adaptive Optics (MCAO) bench in the Atmospheric Simulation and Adaptive Optics Laboratory Testbed (ASALT) at SOR. The enhanced atmospheric turbulence simulator (ATS) on the MCAO bench generates turbulence conditions with as many as 10 phase screens. The atmospheric parameter estimates from data collected with the ASALT Frodo system are presented alongside the estimates made with the laboratory’s Shack-Hartmann wavefront sensor.
