Abstract
An image display apparatus includes a nanotube assembly having a plurality of nanotubes arranged in an array. An optical excitation device is provided adjacent to the nanotube assembly. The optical excitation device includes a diffraction grating and a piezoelectric crystal disposed adjacent to the diffraction grating. A radiation source generates a write beam incident to the piezoelectric crystal, a read beam incident to the diffraction grating, and an erase beam incident to the diffraction grating. When voltage is applied to the piezoelectric crystal, the write beam scans across the diffraction grating and forms a grating pattern in the diffraction grating. The read beam reads the grating pattern as a holographic image on the at least one nanotube. The erase beam erases the grating pattern.
