System for detecting structural defects and features utilizing blackbody self-illumination
First Claim
1. A method of inspecting a coated object, the method comprising:
- maintaining substantially steady state blackbody radiation from the object; and
detecting structural features of the object under the coating based on the blackbody radiation.

Abstract
A system is disclosed which utilizes the substantially steady-state temperature of a coated object, in conjunction with an optical detection system, to selectively view defects and features of the object below the coating without the necessity of transient heating or IR illumination and reflectance imaging. The optical detector, such as an IR camera, may be tailored for the wavelengths at which the coating material is substantially transparent, thereby maximizing the viewing clarity of the defects and features under the coating, and distinguishing them from any spurious features on the top surface of the coating. The present system enables the inspection of small or large areas in real time, without requiring complex image acquisition, storage and image processing equipment and software.
