An Easier Method to Obtain the Sphere, Cylinder, and Axis from an Off-Axis Dioptric Power Matrix

Dr. W. F. Long pointed out that calculations of decentration in spherocylindrical lenses, as well as calculations of combinations of obliquely crossed spherocylindrical lenses, are considerably simplified by the use of matrix methods. In the obliquely crossed lens problem, Long used eigenvalue techn... View More
