Ozone Biocidal Properties and Stimulation of Trichoderma harzianum (strain T-22) When Applied in Combination as an Environmentally Benign Alternative for Methyl Bromide

Not Available Adaptive optics systems for imaging or beam projection through the atmosphere are designed to compensate for the optical effects of turbulence. These effects enter in as phase perturbations distributed along the propagation path. Conventional adaptive optics systems attempt to compensate for these effects by means of phase-only corrections applied at a plane conjugate to the aperture, or slightly behind it. This can be highly effective when much of the turbulence is relatively close to the aperture, as is the case in up-looking applications such as astronomy, but it is less effective when the turbulence is distributed more uniformly along the path, as is the case for the Airborne Laser. We propose to investigate the performance improvement achievable with VCAO and MCAO systems for applications involving near-horizontal paths, and the feasibility of implementing such systems. We would use simulation to investigate the potential performance improvement, and to attempt to develop a practical sensing and controls scheme for an MCAO system. In parallel with these simulation studies, we would attempt to develop a feasible design for an experiment to test the VCAO concept, to be conducted at the Airborne Laser Advanced Concepts Testbed (ABL-ACT).
