Paper Abstract

The technique of laser vibrometry is used to generate vibration images, i.e. data cubes where the target vibration amplitude distribution across the target, for a given vibration frequency, is mapped onto the x-y-plane, and frequency varies along the z-direction. Sample vibration images were taken by laser radars at (lambda) equals 10.6 micrometer (CO2 laser) and (lambda) equals 1.54 micrometer (erbium fiber laser) at ranges over 1 km. The first ever taken vibration images of motorized vehicles at such distances will be presented. Vibration imagery offers new possibilities for target classification, and for investigating and monitoring vibration behavior of large scale structures. Experimental and theoretical comparisons of laser vibrometry techniques with and without spatial resolution capability will be presented.
