Abstract
This paper describes recent technology improvements in Scanning Laser Acoustic Microscopy (SLAM) which make high resolution (25-50 micron) measurements of the spatial dependence of the attenuation coefficient practical. These measurements are not readily obtainable by any other means. Two devices are described and examples of their application to materials characterization and nondestructive testing are presented.
