Abstract:
1. An electronic optical zoom system, comprising: a first lens assembly having a first magnification and a second lens assembly having a second magnification, each lens assembly for collecting and receiving light; an image sensor; a switchable mirror axially aligned with the first lens assembly and having electronically selectable states comprising a reflective state and a pellucid state, and being disposed along a first reflected optical path from the first lens assembly and the image sensor; a reflective surface axially aligned with the second lens assembly; wherein the first lens assembly and the second lens assembly are stationary relative to the image sensor, and a system image magnification can be varied by electronically altering a state of the switchable mirror to: redirect the light from the first lens assembly along the first reflected optical path to the image sensor when the switchable mirror is in the reflective state; and redirect the light from the second lens assembly to the image sensor along a second reflected optical path, through the switchable mirror, when the switchable mirror is in the pellucid state.
