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:
“All is changed. All looks strange to me and gives me a feeling which I would rather get away from, although I know it to be the carrying out of natural laws. And I am not complaining. I am doing the same as many old people have done, I suppose, who have led an active life and suddenly find themselves living without a purpose. Oh, my heart is so full. I could write a big book on the subject of going out of this world gracefully.”
—Maria D. Brown (1827–1927)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
