Assignee: BATTELLE MEMORIAL INSTITUTE
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A multi-spectral inspection (MSI) method performed on an associated electronic item having a printed circuit board (PCB), the MSI method comprising:
controlling an optical imaging scanner to acquire an optical image of the associated electronic item;
analyzing the optical image to identify areas of significance of the associated electronic item;
controlling a functional imaging scanner and an electronic power supply to acquire functional area images of the areas of significance with the associated electronic item powered in accord with one or more test vectors using the electronic power supply;
generating a functional image for each test vector by combining the functional images acquired with the associated electronic item powered in accord with that test vector;
generating a three-dimensional (3D) signature for the associated electronic item comprising a stack of the optical image and the functional images at the one or more test vectors; and
performing at least one MSI analysis by processing the 3D signature using one or more artificial intelligence (AI) classifiers;
wherein the associated electronic item is an instance of a Commercial Off-The-Shelf (COTS) product, and the performing of the at least one MSI analysis includes performing a revision identification analysis by processing the 3D signature using one or more AI classifiers trained on 3D signatures generated for different revisions of the COTS product each labeled by the respective revision.
