Adaptive optics systems and control algorithms can be tested in the laborat
ory with controlled disturbances. We have a micromachined deformable mirror
that we use as a programmable aberration generator. We present a method of
programming the actuator amplitudes so that the wave front reflecting from
the surface will simulate atmospheric turbulence. We present experimental
results that show that we can simulate the Kolmogorov spatial spectrum with
in the constraints of the useful region of the deformable mirror. (C) 2001
