Abstract
An optical ray deflecting means is neutrally supported in and biased in alignment with a window in a fluid filled chamber. The fluid, acting on both the sidewalls of the chamber and the surfaces of the deflecting means, causes the deflecting means to undergo proportional angular motion with respect to an inertial reference system when the chamber is subjected to vibrational angular motion with respect to the reference system. Placement of a deflecting means stabilizer at preselected points along the optical path of an optical instrument having high magnification is disclosed for producing instrument image stabilization.
