Automated HDRI Solves Challenges of Detecting Defects in Highly Reflective Fibers
by Doug Wilson
Presented in Atlanta, GA at IEEE-AVFOP in November 2014
About: HDR (High Dynamic Range) imaging is a cost effective solution for testing fibers with bright cores and lenses, which can have much higher reflectance ratios. The process is implemented using a FastMT system.
Long exposure of fiber with clipped, brightly lit/highly refective core.

Graph of short exposure fiber imageshowing normal core, dark cladding.
Short exposure showing normal core but dark cladding.
