Active Systems
In these systems the change in attitude of the binoculars is sensed electronically, and some part of the system is changed to correct this offset. A lens group may be shifted, or the angle of a fluid filled prism may be changed.

Famous quotes containing the words active and/or systems:
“The most intellectual of men are moved quite as much by the circumstances which they are used to as by their own will. The active voluntary part of a man is very small, and if it were not economised by a sleepy kind of habit, its results would be null.”
—Walter Bagehot (1826–1877)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
