Since the rotation angle dκ is small, the motion of the imaging point can be considered to move on the tangent of the circle. The displacement of each image point on the imaging surface of the rotating image caused by the slight angular offset is shown in Fig. 5. The image coordinate ...
When a question asks about the arc, use the formula ((arc))((circumference))=((central angle))(2π) with the measure of the central angle in radians. Since you're literally looking for the fraction of the arc's length to the circumference of the circle, all that is needed to solve...
