The Lissajous lens: a three-dimensional absolute optical instrument without spherical symmetry.
Optics Express, 2015 We propose a three dimensional optical instrument with an isotropic gradient index in which all ray trajectories form Lissajous curves. The lens represents the first absolute optical instrument discovered to exist without spherical symmetry (other than ...

The Classification of Optical Instruments [PDF]
Journal of the Optical Society of America, 1922 Exception is taken to the classification of optical instruments by the signs of their powers, and an alternative division comprising five classes is proposed, based upon the separation of the four Gaussian constants into two groups according to their signs. This classification cannot be modified by the addition to the system of inverting prisms and the
