Open Loop TV Image Stabilization

The open loop compensation of vibrationally induced image motion via electronic deflections in an image intensifier is only possible if an adequate image motion transducer is available. It is desirable that this transducer should utilize components which are both available and needed for other purposes in the system. Thus, this investigation is limited to gyros. The nature of the errors in rate and rate-integrating gyros and their ac pick-offs are investigated. Finally, a method of obtaining satisfactory outputs from a set of rateintegrating gyros is developed.
