ABSTRACT:
An image stabilized optical system includes a casing, an objective system, an eyepiece system, a gimbal connected to the casing via a shaft and capable of oscillating, an erect prism attached to the gimbal, a motor attached to the gimbal, an inertial rotor supported by a rotating rod of the motor, and a damper attached to the gimbal. The damper includes a viscoelastic member and has a first end attached to the gimbal and a second, free end spaced from the casing and the shaft. An image can be highly stabilized by efficiently suppressing in the damper vibrations (resonance) generated in the gimbal. Further, size, weight, and cost reductions, and easy manufacture of an image stabilized optical system are attained.
