A system and method of detecting, quantifying, and characterizing corrosion and degradation of an article, includes receiving signals indicative of a stack of images of a surface of the article; determining depth and nature of features in the stack of images; generating a surface model of the article in response to the determination of the depth and the nature of features; determining features of interest from the surface model; comparing the features of interest with predetermined information on the article; and characterizing the article as corroded or degraded in response to the comparisons of the features of interest.

Apparatus for detecting corrosion in an article

A system and method of condition based maintenance of a fiber network includes a processor and memory having instructions that when executed cause the system to transmit an optical signal over a plurality of fiber links in the fiber network; receive a response signal in response to the transmitting of the optical signal; and determine one or more condition indicators in response to the receiving of the response signal.

An inspection apparatus includes an imaging unit producing image signals; a processing unit for receiving the image signal; the imaging unit producing a stack of images of an article at different focal lengths in response to the processing unit; the processing unit generating a depth map from the stack of images; the processing unit analyzing the depth map to derive a depth profile of an object of interest; the processing unit determining a surface mean for the article from the stack of images; and the processing unit characterizing the article as degraded or contaminated in response to the depth profile and the surface mean.
