Coherent silica fiber bundles have important applications in medical diagnosis, industrial equipment defects detection, highvoltage transformer winding monitoring, and large field optical systems. The solgel method is used to introduce absorbent into pixel monofilament gap, which successfully solves the problem of crosstalk in bundles. Silica fiber bundles with 600 μm outer diameter, 15 000 pixels, 4.4 μm pixel diameter, and resolution of 113 lp/mm were prepared by onestep multiplefiber process. The results show that there are no dark or broken pixels, no distortion in bundles and the image is clear, which means the coherent silica fiber bundles meet the commercial use requirements.
