Viewfinder based on a Galilean telescope system

摘要

This paper discusses the possibility of introducing the image of a grid (a mark) into the field of view of a Galilean telescope system and of converting such a system into a viewfinder. An explanation is given of the position of the pupils and ports in a Galilean telescope system operating in combination with the eye. Two layouts of Galilean viewfinders are proposed. © 2005 Optical Society of America
