Abstract:
1. A fiber end-surface detection device, comprising: a first light source positioned to illuminate a first prism adapted to reflect light from the first light source toward the fiber end surface at a first illumination angle; a second light source positioned to illuminate a second prism adapted to reflect light from the second light source toward the fiber end surface at a second illumination angle, the second prism positioned between the first prism and the fiber end surface; a vision device for observing a reflection of the fiber end-surface under illumination from the first light source at the first illumination angle and under illumination from the second light source at the second illumination angle, wherein the reflection passes through the first and second prisms toward the vision device; and a controller for alternately illuminating said first light source and said second light source, for operating said vision device to take images of the fiber end-surface under said alternate illuminations and for operating said vision device to superimpose said images of the fiber end-surface taken under said alternate illuminations, wherein said first and second light sources are located on opposite sides with respect to the vision device position and wherein said fiber end-surface is rounded.
