Abstract:
A method of projecting an image is provided. The method includes the step of providing a first light source, the first light source emitting light at a first polarization. A second light source is provided adjacent the first light source, the second light source emitting light at a second polarization. A digital mirror device is provided (DMD), the DMD having a first axis. A mirror is provided optically disposed between the first light source, the second light source and the DMD, the mirror being adjacent the DMD. A first light is emitted from the first light source. The first light is reflected with the mirror onto the DMD. A second light is emitted from the second light source after the first light is emitted. The second light is reflected with the mirror onto the DMD.
