Laser projection system with improved bit depth |
| 摘要 |
An apparatus and method for despeckling that includes a green laser diode assembly, a pulsed laser with a repetition rate of less than 100 kHz, and stimulated Raman scattering light formed in an optical fiber. The laser diode light and stimulated Raman scattering light are combined to form a projected digital image. The green laser diode assembly or the pulsed laser is switched to improve the bit depth of the projected digital image. |

1. An optical apparatus comprising:
a laser diode assembly that generates a first green laser light; a first pulsed laser that generates a second green laser light; and a first optical fiber; wherein the first pulsed laser has a pulse repetition rate of less than 100 kHz; the second green laser light is focused into the first optical fiber; the first optical fiber generates a first stimulated Raman scattering light that enhances an aspect of a light output of the first optical fiber; the first green laser light and the first stimulated Raman scattering light are combined to form a projected digital image; and the laser diode assembly is switched to generate one bit of bit depth in the projected digital image. |
