| 摘要 |
A lateral illumination optical fibre (1) comprises a light-conducting core (2) oriented in a main direction of propagation (M), optical means (11, 12) arranged in or on the core for emitting visible lateral luminous radiation (5) in a radial direction when the optical means (11, 12) are irradiated with exciter radiation (4) propagating in the main direction of propagation (M) in the core, wherein the optical means comprise first optical means (11) and second optical means (12), and the first and second optical means (11, 12) are made to emit lateral luminous radiation (51, 52) each by a diverging exciter radiation (41, 42). |
