System and method of evaluating an object using electromagnetic energy

A method of evaluating an evaluation object with respect to at least one reference object, the method comprising:

• driving at least one physical source of a plurality of physical sources with an electromagnetic forcing function as a plurality of logical sources for each of at least some of the physical sources being driven;
• receiving an electromagnetic response from at least a portion of an illuminated region of the evaluation object;
• and
• converting the electromagnetic response to a response signal indicative of the response of the illuminated portion of the evaluation object.

An electronic-readable medium having embodied thereon a program, the program being executable by a machine to perform a method for evaluating an evaluation object with respect to at least one reference object, the method comprising:

• driving at least one physical source of a plurality of physical sources with an electromagnetic forcing function as a plurality of logical sources for each of at least some of the physical sources being driven wherein each of the logical sources is characterized by a respective band of emission, and at least two of the logical sources of each of the physical sources have different bands of emission from one another;
• receiving an electromagnetic test response from at least a portion of an illuminated region of the evaluation object;
• converting the electromagnetic response to a test response signal representative of the test response of the illuminated portion of the evaluation object;
• and
• comparing the test response signal corresponding to the evaluation object with a stored reference response signal indicative of a response by the at least one reference object to illumination by electromagnetic energy.

A system for evaluating subject objects, the system comprising:

• a plurality of physical sources operable to emit electromagnetic energy, at least some of the physical sources of the plurality of physical sources having different emission spectra than other of the physical sources;
• driver electronics drivingly coupled to the plurality of physical sources, the driver electronics configured to drive at least two of the physical sources of the plurality of physical sources in a plurality of selected sequences;
• and
• a sensor configured to receive an electromagnetic response from at least a portion of at least one evaluation object illuminated by at least one of the physical sources of the plurality of physical sources and convert the electromagnetic response to a response signal.
