Abstract
(EN)
This light source device generates laser light that enters a microlens array comprising a plurality of microlenses arranged in two directions that are orthogonal to each other, and has a plurality of light sources that output the laser light. The light sources form elliptical light source images on an entry surface of the microlens array, and the long-axis direction of the light source images intersects both of the two directions.
(FR)
Ce dispositif de source de lumière génère une lumière laser qui entre dans un réseau de microlentilles comprenant une pluralité de microlentilles disposées dans deux directions orthogonales l'une par rapport à l'autre, et présente une pluralité de sources de lumière qui émettent la lumière laser. Les sources de lumière forment des images de source de lumière elliptique sur une surface d'entrée du réseau de microlentilles, et la direction d'axe long des images de source de lumière coupe les deux directions.
(JA)
互いに直交する2つの方向に並べて配置された複数のマイクロレンズを備える、マイクロレンズアレイに入射するレーザー光を生成する光源装置は、レーザー光を出力する複数の光源を有する。ここで、マイクロレンズアレイの入射面における光源の光源像が楕円状であり、光源像の長軸方向が、2つの方向のいずれとも交差している。
