The wide frequency coverage provides high-resolution distance resolution
, so the handheld analyzer can conduct more accurate Distance-To-Fault (DTF) measurements.
An important improvement with this method is the exploitation of stripe flanks for improved triangulation accuracy: digital projectors and cameras allow to generate and measure 'gray value' gradients at extreme accuracy and deliver an improvement in triangulation and distance resolution
by up to two orders of magnitude.
For previous OTDR's, best-case distance resolution
is limited to the sample spacing.
001 mm distance resolution
(unchanged), and force sampling at up to 14 kHz (3 kHz).
Coupled with the higher distance resolution
and Nikon's renowned optics, these features allow for more effective and accurate work in such situations as:
