1. A variable luminosity visual display system comprising:
- (a) a light source for generating light along an optical path; and
(b) a spatial light modulator located in said optical path, said spatial light modulator including a plurality of elements, each said element individually and digitally controlled between a first transferring state and second non-transferring state and then between said second non-transferring state and said first transferring state for an associated portion of said light at an operating frequency equal to or higher than the critical flicker frequency of the human eye, wherein said associated portion of said light is controlled by the total amount of time said element resides in said first transferring state.

Abstract
A digitized video display system has a spatial light modulator which has individual elements which are controllable to produce individual beams which form an image. The individual elements are controllable at a frequency which is less than the critical flicker frequency of the human eye to produce individual beams which form an image. The individual elements are controlled to provide a luminosity control over individual pixels or voxels of the image.

16. A method of displaying an image comprising the steps of:
-
(a) generating light along an optical path; and (b) controlling elements individually and digitally between a first transferring state and second non-transferring state, and then between said second state and said first state for an associated portion of said light at an operating frequency equal to or higher than the critical flicker frequency of the human eye, wherein said associated portion of said light is controlled by the total amount of time said element resides in said first transferring state. - View Dependent Claims (17, 18, 19)

20. A variable luminosity visual display system comprising:
-
(a) a light source for generating light in an optical path; (b) a spatial light modulator located in said optical path, said spatial light modulator having a plurality of indivicually controllable elements; (c) each of said elements having a first state for allowing an associated portion of said light to impinge on a remote surface and a second state for preventing said associated portion of said light from impinging on said remote surface with each element selectably controllable between said first and second states a plurality of times at a frequency equal to or greater than the critical flicker frequency of the human eye, wherein the perceived intensity is controlled by the total amount of time said element resides in said first transferring state. - View Dependent Claims (21)
