Image-tremble-correcting system for optical instrument

摘要

In an image-tremble-correcting system for an optical instrument, having an optical focussing system for producing a focussed image, to correct a tremble of the focussed image caused by an oscillation of the optical instrument, a movable optical tremble-correction system is assembled in the focussing system of the optical instrument. An X-Y rectangular coordinate system which is defined on a plane perpendicular to the optical axis of the focussing system, the origin of the coordinate system coinciding with the optical axis of the focussing system, the X- and Y-axes thereof defining an angle of 45° with a horizontal axis and a vertical axis defined on the plane when the optical instrument is positioned at a usual attitude. The movable optical tremble-correction system being movable along the X-axis and the Y-axis of the X-Y rectangular coordinate system to the same extent.
