1. A system that characterizes health of a lubricant circulating in a lubrication circuit of an engine, the system comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the system to function as:
a sensor array coupled to the lubrication circuit in the engine, the sensor array providing optical or visual properties that depend on the health of the lubricant, and the sensor array producing a sensor array output;
a signature component that receives the sensor array output and generates a digital signature; and
an analysis component that receives the digital signature generated by the signature component and that compares, via a machine learning algorithm, the digital signature with a baseline digital signature corresponding to a desired health-level of the lubricant, in order to characterize the health of the lubricant, the analysis component outputting a value representing the health of the lubricant.
