The characteristics of wavefronts propagated through turbulence and the resulting images are discussed. Hot wire anemometry and holographic interferometry techniques are used to measure wavefront distortion. A model is developed to describe the associated images. The effect of viewing wavelength is examined in detail. A short wavelength limit is found in which the image size is aerodynamically limited and independent of wavelength. The distortion weakens with increasing wavelength until long wavelengths are reached where the image size is diffraction limited. The behavior of imaging systems throughout this wavelength region and its dependence on aero-optic parameters is examined.
