Figure 3: Bright- and dark-field microscopy based upon multimode fibre image transfer.
From: Exploiting multimode waveguides for pure fibre-based imaging
The top row shows images obtained by direct imaging of sample (CCD1, see Fig. 5) whereas the bottom row presents the images reconstructed from the randomized output light at the other end of the fibre and detected by CCD2 (Fig. 5). (a–f) Imaging of laser fields generated by scanning a laser beam focus along the input fibre facet by an AOD. (g–l) Bright-field images of empty sample (g,j) and 10-μm polymer particles in a water solution (h,i and k,l). (m–r) Dark-field images of empty sample (m,p) and polymer particles of 10 μm (n,q) and 1.8 μm (o,r) in diameter, respectively.
