 Overly pedantic into? 

A layman reading this, ""...so that when an imaging system (a camera or an eye) is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present.""

sounds kind of ridiculous, esp the ""will be seen even when the object is no longer present"" part.  Photography could be described the same way... to a bushman perhaps.  It's like defining an automobile as a metal box that you sit in and after turning a key and moving some controls around, you get out and you are in a different place that you were before.
