Abstract
An image-forming system with enhanced gray levels, including: a primary beam of light having a primary intensity value, a secondary beam of light having a secondary intensity value significantly less than the primary intensity value; a first modulator array of discrete devices receiving the primary beam of light and producing an output with coarse gray levels, a second modulator array of discrete devices receiving the secondary beam of light and producing an output with fine gray levels; a controller for synchronously controlling the first and the second modulator array; and optics that combine the output with fine gray levels and the output with coarse gray levels to form an image with the enhanced gray levels.
