Abstract
A system for evaluating subject objects includes at least one physical source (118) operable to emit electromagnetic energy and driver electronics (111) drivingly coupled to at least one physical source. The driver electronics is configured to drive at least one physical source as a number of logical sources, using an electromagnetic forcing function. The number of logical sources is greater than the number of physical sources In addition, the system includes a sensor (116) configured to receive an electromagnetic response from at least a portion of an evaluation object illuminated by one or more physical sources operated as logical sources, and convert the electromagnetic response to a test response signal indicative of the electromagnetic response of the evaluation object
