Bonjour Michel
,
ca devrait répondre à ta question :
Laser phosphor illumination, such as what’s used in the Christie® GS Series and Captiva Series, uses a blue laser diode as the light source instead of a high intensity discharge (HID) lamp. To generate the three primary colors, the laser diode shines laser light onto a phosphor wheel to create yellow light, while blue laser light passes through an opening in the phosphor wheel. The projector then sends the yellow light through a color wheel to generate red and green, while the blue laser light passes through a diffusion window. These red, green and blue colors are then directed onto an imaging surface, such as a DLP® chip which directs the light through a lens and onto the projection screen.
