Claim:
1. A light source system comprising: a light generating device which sequentially generates a first light and a second light; a light division system which divides the first light from the light generating device into a light in a first wavelength range and a light in a second wavelength range and outputs them along a first light path and a second light path, respectively, and which outputs at least a part of the second light from the light generating device along the first light path; a first spatial light modulator, which modulates the lights outputted along the first light path of the light division system; and a second spatial light modulator, which modulates at least a part of the lights outputted along the second light path of the light division system, wherein the light division system includes a light filter device and a second drive device for driving the light filter device, the light filter device having a first segment, a second segment and a third segment, wherein the first segment transmits a part of the second light and outputs it along the first light path and reflects another part of the second light and outputs it along the second light path; the second segment transmits the light in the first wavelength range in the first light and outputs it along the first light path, and reflects the light in the second wavelength range and outputs it along the second light path; and the third segment reflects the light in the first wavelength range in the first light and outputs it along the second light path, and transmits the light in the second wavelength range and outputs it along the first light path; wherein the light generating device further includes a first control device for controlling the second drive device such that at least a part of the second segment and at least a part of the third segment are sequentially disposed on an output path of the first light, and at least a part of the first segment is disposed on an output path of the second light.
