Abstract
This thesis explores the use of a pointed seeker lens
designed using a spherically symmetric gradient refractive
index (GRIN) . The design helps to solve the current design
conflict between optical quality and aerodynamic drag inherent
in hemispherical seeker lenses. Equations for lens
design and the evaluation of off-axis lens performance have
been developed for both a homogeneous version and a GRIN
version of the pointed seeker lens. The homogeneous lens
is used as a comparison and a check for the GRIN lens. A
FORTRAN program (GISL) has been written and employed to
evaluate and compare both the homogeneous lens and many different
configurations of possible GRIN lens designs. Results
indicate that the GRIN lens has highly superior off-axis imaging
performance as compared to the homogeneous lens.
