EXERCISE 1.2-3
Sensation Aberration-Free Imaging Surface. Determine theequation of a convex spherical (nonspherical) surface between mediaof refractive indexes n1 and n2 such that all rays (not necessarilyparaxial) from an axial point P1 at a distance z1 to the left ofthe surface area image onto an axial point P2 at a distance z2 tothe right of the surface [Fig. 1.2-12(a)]. Hint: In accordance withFermat's principle the optical pathlengths between the two pointsmust be equal for all paths.
