"Websystems. From an educational point of view a good question to ask is how these reflective systems are designed. In this paper we discuss reflective cameras that are unobscured and that have a wide-field of view at a relatively fast optical speed. Historically, one way to design these systems is to start with a well " - Optics point of view
