What is it about?
The optical fibre illuminator is a special construction of light source. The optical fibre technology allows guiding the light using a total internal reflection phenomenon. Thanks to that, it is possible to guide the light in flexible optical fibre structure for the long distances. The light source can be therefore spatially separated from the illuminated area. Additionally, the optical fibers characteristic such as spectral attenuation, directional emission characteristic can be used for special illumination applications.
Why is it important?
The significance of presented in the paper construction is based on white light emission which was obtained using fluorescence of dyes incorporated directly in polymeric fibre structure. This solution causes the light emission directly from the lateral optical fibre surface. In such case, the directional emission characteristic is different in comparison with typical optical fibers illuminators which emit the spotlight according to emission cone from the fibre tip. The fluorescence phenomenon causes diffused light emission which reduces glare and harsh shadows. This can be especially useful in medical observation.
