A fibre bundle confocal microscope or endoscope (200), comprising a light source (142) for providing a beam of light (160), a coherent fibre bundle of optical fibres (152), a scanner (202) for receiving the beam and scanning the beam over a proximal end of the bundle (162), so that the beam is launched into a plurality of the fibres sequentially, a plurality of the fibres thereby acting sequentially as an at least one delivery fibre (204), a spatial filter (172), and a photodetector (174) operatively associated with the spatial filter to receive return light from one or more of the fibres. The return light from the delivery fibre is excluded from the photodetector by the spatial filter. |
