<p>The invention discloses an optical assembly used for multi-angle illumination of line scanning and a light source system using the same. The optical assembly comprises a first transparent assembly, a second transparent assembly and a light formation diffusion film. The first and second transparent assemblies are provided with a stereo pattern on one surface respectively, so that light entering the surfaces can be collected, and the stereo patterns are oppositely arranged. The light formation diffusion film is disposed at one of the following positions of between the first transparent assembly and the second transparent assembly and contacted with the first and second transparent assemblies, non-stereo pattern surface of the first transparent assembly, and non-stereo pattern surface of the second transparent assembly. Thus, the optical assembly achieves an object of multi-angle illumination, weight of assemblies required by the optical assembly is reduced, and size of the assemblies required by the optical assembly is reduced also.</p> |
