Abstract
Systems and methods for identifying thermal response of a test structure. An example of the system includes a device that generates a excitation beam, a scanning device that scans the thermal excitation beam over a test structure, and a detector that detects acoustic waves produced scanning by the test structure. The system also includes a display device that generates and displays an image based on the detected acoustic waves. A second detector detects a reflection of the beam off of the test structure and the display device generates and displays an image based on the detected reflection.
