Abstract:
An image capture system is configured to automatically focus upon an object (113) electronically, without moving mechanical parts. In one embodiment, a focal length alteration device (104), examples of which include an electronically switchable mirror (3041,3042) or an interference layer (204), is disposed between a lens assembly (102) and a reflective surface (103). The focal length alteration device (104) is configured to alter the distance light travels from the lens assembly (102) to the image sensor (101). In another embodiment, a light redirection device (1003), such as a phase shifting mirror (703), is configured to alter phases of various polarizations of light. An image processing circuit (105) then resolves images into a single, focused, composite image (113).
