System and method for converting between Keplerian and Galilean telescope magnification

摘要

A system including a first refractive lens doublet comprising a first fixed focal length lens and a first liquid-based lens, the first liquid-based lens responsive to transition between a convex configuration and a concave configuration when electronically actuated, and a second refractive lens doublet comprising a second fixed focal length lens and a second liquid-based lens, the second liquid-based lens responsive to transition from a convex configuration to a concave configuration when electronically actuated. A focal length of the first liquid-based lens and a focal length of the second liquid-based lens are switched between a positive focal length and a negative focal length when electronically actuated to provide a net focal length to produce a varied collimated magnification of light.
