| 摘要 |
The present invention discloses an optical assembly of multi-angle illumination for a line scan, and a light source system using the same. The optical assembly includes a first transparent element, a second transparent element, and a light shaping diffuser (LSD). The first and second elements are put together on a surface and form three-dimensional patterns from incident light. The three-dimensional patterns are arranged to face each other. The light shaping diffuser is arranged between the first transparent element and the second transparent element while contacting the first transparent element and the second transparent element. Otherwise, the light shaping diffuser is arranged on one side of either the first element or the second element, which does not have the three-dimensional pattern. The optical assembly is able to not only perform multi-angle illumination but also reduce weight and occupied volume required for the optical assembly. |
