An Optical Device Which Compensates for Linear Shift in Panoramic Strip Aerial Photography with Horizontal Scanning Axis

摘要

This optical device which compensates for linear shift in panoramic strip aerial photography with horizontal scanning axis, contains a double wedged optical compensator with the wedge angles corresponding to the compensation velocity. To compensate for the variable image velocity, the compensator rotates in front of the objective at the same velocity as the projected pencil of rays. (Author)
