PROJECTION APPARATUS PROVIDING REDUCED SPECKLE ARTIFACTS |
摘要 |
<p>A projection apparatus for producing color images having reduced speckle artifacts comprising: at least three narrow band light sources having first, second and third visible wavelength bands; a digital image source providing color digital image data; at least one spatial light modulator for forming a color image using light responsive to the color digital image data; a projection display surface including a reflective layer that reflects incident illumination in the first, second, and third wavelength bands; and a fluorescent agent that absorbs a fraction of the incident light in the first visible wavelength bands and emits light in a corresponding first emissive visible wavelength band; and a projection lens that projects the color image onto the projection display surface; wherein return light from the projection display surface contains light in both the first incident visible wavelength band and the first emissive visible wavelength band, thereby reducing speckle artifacts.</p> |
