Conformal Optics: Key Issues in a Developing Technology
Conformal optical elements offer the promise of enhanced aircraft and missile performance, as well as the potential of improved commercial applications such as microlithography and precision illumination. To turn potential into reality, a number of technical issues must be understood and solved in the areas of optical modeling, optimization, fabrication, and testing.

"Daddy—what's a digital signal?" Yikes! How do you explain a question like that? Analog and digital signals are all around us, but it's pretty hard to get across the basic concepts to kids or people with non-technical backgrounds. For instance, you can say, "Well, vinyl records are analog and CDs are digital," but it won't help because most kids these days have never even seen a vinyl record.
