Optical Propagation Through a Turbulent Jet.
Abstract
A fast optical tomography system has been used to investigate a heated round jet acoustically excited in axisymmetric and helical modes. This flow diagnostics reveals the development and interaction of large-scale vortices in the near-field region of the jet. In a complementary experimental study of prediction-based adaptive optics, Linear Stochastic Estimation of optical beam deflection produced by the jet has been used in an open-loop control system. a piezoelectric steering mirror wa controlled to minimize beam deflection based on temperature inputs. The results indicate that a multi-aperture adaptive- optic control system may be based on multi-point temperature measurements.
