Abstract
We describe the current performance of an adaptive optics testbed for optical communication. This adaptive optics system allows for simulation of nighttime and daytime observing on a 1-m telescope with a 97-actuator deformable mirror. In laboratory-generated seeing of 2.1 arcsec (at 0.5 µm), the system achieves a Strehl of 21 percent at 1.064 µm (210-nm rms wavefront). Predictions of the system’s performance based on real-time wavefront sensor telemetry data and analytical equations are shown to agree with the observed image performance.
