Light source system with multiband filters and relay lens assemblies for a stereoscopic image

摘要

A light source system for stereoscopic image is disclosed, which includes a first multiband filter, a second multiband filter, a first relay lens assembly, a second relay lens assembly, a light source module, a light outputting portion and a light valve device. The first and the second relay lens assemblies are disposed between the first multiband filter and the second multiband filter. The light source module and the first multiband filter are together disposed at one side of the first relay lens assembly. The light outputting portion and the second multiband filter are together disposed at one side of the second relay lens assembly. The light valve device is disposed between the first and the second relay lens assemblies. Therefore, the light source system configures the light path by controlling the light valve device and produces beams with different bands.
