Simulation of Power Distributions in Progressive Addition Lenses
This study is to simulate the whole-surface power distributions in progressive addition lenses (PALs) by using a governing conicoid equation to generate the front and back surface shapes. The results show that the spherical equivalent power and astigmatism are strongly affected by the add power, progressive corridor length, and asphericity.

General Theorem of the Variation of Aberrations of Optical Lenses
A brief review of our research on modelling and
evaluating the variations of the primary optical aberrations
(including the Seidel aberration, chromatic aberrations and
secondary spectrum) of conceptual thin and thick lenses is
given. Further, we have proved that lenses with the same focal
length but different thicknesses may provide equivalent
aberrations under some conditions.

Generalized Aberration Reduction Procedure of a Concave Diffraction Grating for Hyperspectral Imaging
An optimization process to control the aberration of a concave grating is developed. The approach has a dramatic reduction in aberration and great improvement in spectral resolution.

The Study of Alvarez Lens for Reducing Spherical Aberration
An unequal ratio Alvarez lens with minimum lateral shift has been designed, which can minimize the longitudinal spherical aberration. The design consists of two-group lens pairs with unequal ratio structure. The rms spot size radius decreases from 3.15 μm for the single lens-pair to 1.75 μm for two-group lens pairs.
