1. Prescription-Based Optical Modeling
... Optical designers have long relied on geometric optics, or ray-tracing, to predict performance of optical instruments. ... As commonly implemented, physical optics codes unfold an optical system into a simplified linear sequence of ``thin lenses,'' which collapse the phase effects of optical elements into a plane. ... This approach accurately determines the effects of vignetting, aberrations and induced aberrations, based on the actual optical instrument geometry and prescription. ...

... In this poster we propose a hypothesis that within fixed assumptions about internal physics (opacity, thermodynamics, nuclear reactions) a strict relation between the surface helium abundance and the entropy of the adiabatic part of the convective zone exists for all solar models. This hypothesis is verified with models under simplified physics (Christensen­Dalsgaard 1988) and with six evolutionary models computed by Christensen­Dalsgaard (1992). ... 1990, Christensen­Dalsgaard 1991). ...
