A method and apparatus for examining the electrochemical kinetics occurring at the surface of a galvanized steel cable undergoing fatigue in the presence of a corrosive environment allows the prediction of the corrosion life of the cable. In one embodiment, an apparatus for detecting localized corrosion in a cable is provided undergoing mechanical fatigue, comprising a weir cell containing an electrolyte and a reference electrode, one or more pulleys, and a motion control device. In other embodiments, methods for detecting and monitoring the electrochemical response of corrosion coupled to fatigue in a galvanized steel cable are provided wherein the potential between a reference electrode and a moveable cable under tension and undergoing fatigue are recorded and/or monitored. In further embodiments, a method and apparatus are provided for inspecting entire runs of cable for localized corrosion, zinc porosity, and corrosion inhibition efficiency. In still further embodiments, methods for the selective application of corrosion protectants to critical cable regions are provided which extend cable corrosion life.

A system includes a master oscillator configured to generate a low-power optical beam. The system also includes a planar waveguide (PWG) amplifier configured to generate a high-power optical beam using the low-power optical beam. The PWG amplifier has a larger dimension in a slow-axis direction and a smaller dimension in a fast-axis direction. The system further includes at least one adaptive optic (AO) element configured to modify the low-power optical beam along the slow-axis direction and to modify the low-power optical beam along the fast-axis direction. In addition, the system includes a feedback loop configured to control the at least one AO element. The modification in the slow-axis direction can compensate for thermal-based distortions created by the PWG amplifier, and the modification in the fast-axis direction can compensate for optical misalignment associated with the master oscillator and the PWG amplifier.

The concepts, systems and methods described herein are directed towards encrypting optical signals prior to the optical signals being sensed, for example, by a sensor. An optical phased array (OPA) may be disposed between an optical chain and a sensor to encrypt an optical signal being sensed before the signal is received at the sensor. The method includes receiving an optical signal having a plurality of beams organized in a first arrangement at an optical phased array, encrypting the optical signal in the optical phased array by steering or otherwise phase shifting the plurality of beams from the first arrangement to a second arrangement, transmitting the plurality of beams in the second arrangement from the optical phased array to a sensor and sensing the encrypted optical signal having the plurality of beams in the second arrangement at the sensor.
