Fibre Light

Light from a fibre   Fibre Interference Intereference pattern of blue laser light from multiple cores of a bespoke optical fibre. Each core has been acid etched, forming a concave pit. Each concave pit acts somewhat like a lens. The far end of the fibre is illuminated with a laser source over multiple cores. The …

Multiplexed fibre sensing

  This Scanning Electron Microscope image shows a multicore optical fibre probe consisting of 19 individual cores which guide light, comparable to the multiple electrical wires within a cable. The fibre cores have been etched to produce concave pits, and multiple types of silica (glass) microsphere sensors embedded. This produces a miniaturised sensor with the …
