The decay of velocity and density fluctuations in buoyancy influenced turbulence generated by a biplanar grid, towed horizontally through a stably stratified fluid with uniform optical index of refraction was measured for three different constant den

Adaptive Optics.
In late 1996, the existing six mirrors of the Multiple Mirror Telescope (MMT) will be replaced by a single 6.5-m mirror, which is now being polished at the Steward Observatory Mirror Lab. Earlier work [1, 2] has shown that an adaptive optics system u

We have developed low-cost tip-tilt and segmented deformable mirrors for use at astronomical telescopes. The design of the mirrors and performance test data will be presented.

Simulations and earlier off-line experimental data suggest1,2 that a wavefront sensor based on an artificial neural network processor may provide a simple way to measure low-order wavefront distortion in an astronomical telescope. The neural network

We have recently finished development of an adaptive optics system intended to be a versatile instrument for imaging and beamforming from visible to infrared wavelengths. In particular, it can be used to perform broadband imaging using a visible lase
