Abstract
Abstract A two-dimensional array of small, thin, flexible, metalized mirrors are mted atop supports on one side of a photoelectric layer. A visible light or infrared image on the other side of the layer induces an electron image (charge pattern) beneath the mirrors. The mirrors deflect towards the layer in accordance with the charge pattern. Light projected onto the mirrors is reflected and forms an image dependent on the deflections thereof.

Claim 1
Independent Claim
153 words
An electro-mechanical image converter including: a photoelectric layer having essentially planer and parallel photon-image and electron-image sides; an array of deformable, light-reflective elements on said electron-image side of said photoelectric layer, wherein said elements each include an insulating support with one end on said electron-image side of said layer and with at least a thin metallic leaf on the other end; means for establishing a voltage potential between said layer and said array and whereby a photon image on the photon-image layer induces an electron image on the photon-image side thereof and further whereby said elements deflect toward said electron-image side of said layer in accordance with the electron image thereon; a light source; means for projecting said light from said light source onto said elements and for forming an image of light reflected therefrom; and means for reversing said voltage potential whereby said elements of said array return to their undeflected positions.
