摘要：A variable focus system that includes an electrovariable optic (EVO) and acontroller operatively configured for changing the focal configuration of the EVO. TheEVO includes a plurality of movable optical elements that may be moved substantially inunison with one another so as to change either the focal length of the EVO, the direction
of the focal axis of the EVO, or both, depending upon the needs of a particular
application. The variable focus system may be used in conjunction with an image source toconstruct a 3D floating image projector that projects a series of 2D image slices of a 3Dimage onto corresponding respective image planes in succession rapidly enough that a3D floating image is perceived by a viewer.
