Abstract

We present a progress report on the SOAR Adaptive Module, SAM, including some results of tests of the Natural Guide Star mode: image correction in the visible, performance estimates, and experiments with lucky imaging. We have tested methods to measure the seeing and the AO time constant from the loop data and compared the results to those of the stand-alone site monitor. Measurements of the instrument throughput and telescope vibrations are given. We report progress on the Laser Guide Star system implementation, including tests of the UV laser, test of the beam transfer optics with polarization control. We present the designs of the laser launch telescope and laser wavefront sensor.
