Abstract
A dual phosphor wheel projection system is provided. A first dichroic mirror directs blue light from a first blue laser to a second dichroic mirror which directs the blue light to at least one integrator. The first dichroic mirror directs blue light from a second blue laser to a first phosphor/phosphor wheel, which converts the blue light to longer wavelengths that includes red light. The second dichroic mirror directs the red light to the integrator and transmit others of the longer wavelengths. The integrator combines the red light with red light from a red laser. A third dichroic mirror directs the red light from the red laser to the integrator and directs blue light from a third blue laser to a second phosphor/phosphor wheel, which converts the blue light to respective longer wavelengths that includes green light. The third dichroic mirror transmits the green light to the integrator.
