Vibrating varifocal mirrors for 3-D imaging

As technology advances, the interactions between man and machine become more complex. A reliable three-dimensional man-machine interface could help alleviate some of the complexity; but an effective 3-D display has, so far, eluded technologists. Thus, we have been forced to make unnatural compromises when dealing with data that are essentially three-dimensional in nature. This article describes a system that may meet the autostereoscopic display requirements in many situations.
