Paper Abstract

The refractive irregularities that are responsible for the atmospheric degradation of optical images arise from variations in temperature of the atmosphere. We present a non-mathematical, physically based description of these irregularities and how they contribute to the degradation of an image. Irregularities near the image contribute only through the distortion of the wave front, thereby distorting or spreading the image of a point source. More distant irregularities produce, in addition, scintillations or fluctuations in the intensity of the light. The random apodization resulting from scintillations further degrades the image.
