Comparison of uncorrected and corrected exposures showing the effects
of image stabilization on image quality. The exposures on the left show the move-
ment of the spots during the integration, while the stabilized images (right) show im-
proved resolution.
The use of nonoptical sensors to remove vibration from the optical system is
ideal for low-light applications and situations where wind buffeting of the optical
system is a problem. However, this type of mechanical-vibration sensor is com-
pletely insensitive to the angle-of-arrival fluctuations in a wavefront aberrated by
the atmosphere. The result of removing the effects of vibrations on the optical
system is shown in the images in Fig. 8.8.
