Abstract
Techniques for optical monitoring of corrosion are described herein. In an example embodiment, an optical monitor includes a target disposed within the optical monitor and exposed to ambient air, where exposure to the ambient air produces a change in an optical property of the target. The optical monitor also includes a light emitter to illuminate the target and an optical detector to generate a signal based on light reflected from the target. A processing device disposed within the optical monitor is configured to activate the light emitter and to receive and process the signal from the optical detector.
Claims10
A data center server comprising:
- one or more components;
- and
- an optical monitor affixed to the data center server, the optical monitor comprising:
- a chamber exposed to ambient air;
- a target housed in the chamber, wherein the target is representative of the one or more components of the data center server, and wherein exposure to the ambient air produces a change in an optical property of the target due to corrosion;
- a light emitter configured to illuminate the target;
- an optical detector configured to generate a signal based on light reflected from the target;
- and
- a processing device configured to activate the light emitter, to receive the signal from the optical detector, and to determine a level of corrosion of the one or more components based on the signal from the optical detector.
