초록

In a nondestructive thermographic evaluation technique, a selected amount of energy is applied to a first object having a known surface structure. An image of the first object is formed within the dynamic limits of an imaging device which preferably includes a white bar. The image is stored on a recording device and enhanced using an image processor. The selected amount of energy is then applied to a second object which is imaged by the imaging device, and the image of the second object is also enhanced. The images of the first and second objects are the...

청구항

A method for thermographically evaluating objects, comprising the steps of: (a) applying a selected amount of energy to a first object having a known surface structure in order to raise the surface temperature of the first object; (b) imaging the first object having a known surface structure and ensuring that the thermographic imaging device substantially reaches the maximum limit of its dynamic range when imaging the known surface structure; (c) recording on a storage device the image of the first object having the known surface structure; (d) enhancing...
