Method and Apparatus for Non-Destructively Determining Features in a Planar Specimen

Abstract

A method and apparatus for non-destructively determining features in a planer specimen includes providing a heat impulse to the specimen, detecting temperatures in the specimen at a plurality of locations, and imaging the specimen from the detected temperatures. A laser can be used to provide a single or a plurality of heat impulses to the specimen. Temperatures in the specimen can be detected utilizing a contact sensor array or a remote infrared detector. These sensors are joined to a data processing device to image the specimen utilizing the detected temperatures.
