<p>PROBLEM TO BE SOLVED: To provide an optical member of polygonal illumination used for row scanning that can significantly reduce the weight and volume of a translucent element and supplies illumination light of high luminance to a target area from an illumination light source, and to provide a light source system using the optical member.SOLUTION: The optical member of polygonal illumination used for row scanning comprises: a first translucent element 110; a second translucent element 112; and a diffusion film 120. The first translucent element 110 includes, on its surface, a stereoscopic pattern 115a for condensing light beams coming from the surface only in the first dimension. Similarly to the first translucent element 110, the second translucent element 112 includes, on its surface, a stereoscopic pattern 115b for condensing light beams coming from the surface only in the first dimension. The surface of the stereoscopic pattern 115b of the second translucent element 112 faces the surface of the stereoscopic pattern 115a of the first translucent element 110. The diffusion film 120 diffuses the incident light beams in the second dimension.</p> |
