Abstract:
(EN) This optical device is provided with a first optical element that spreads incident light in a first direction, and a second optical element that converges the light from the first optical element in a second direction that is perpendicular to the first direction. The second optical element has a refractive index distribution in the second direction and is formed so that the distance from a light incident surface to a light emission surface changes in the first direction.
(FR) L'invention concerne un dispositif optique comprenant un premier élément optique qui propage une lumière incidente dans une première direction, et un second élément optique qui fait converger la lumière provenant du premier élément optique dans une seconde direction perpendiculaire à la première direction. Le second élément optique présente une distribution d'indice de réfraction dans la seconde direction et est formé de telle sorte que la distance entre une surface d'incidence de lumière et une surface d'émission de lumière change dans la première direction.
(JA) 光デバイスは、入射光を第1の方向に広げる第1の光素子と、第1の光素子からの光を、第1の方向に直交する第2の方向に収束させる第2の光素子とを備える。第2の光素子は、第2の方向に屈折率分布を有し、光入射面から光出射面までの距離が、第1の方向において変化するように形成されている。
