Abstract
A flexible membrane mirror is driven by a waveform synchronized to a display of a sequence of two-dimensional images on a CRT screen so that a viewer perceives a three dimensional image. The driving waveform is characterized by low noise and a bright image. The driving waveform can be a composite of a triangle wave and a sinusoid.
