Abstract: A gravitational wave generating device is positioned on one side of a material object and a gravitational wave detection device is positioned on the other side of the material object. The intervening material object's texture and internal structure will modify the gravitational wave's polarization, amplitude, speed, frequency, or other characteristics and serve to image the material object's texture and internal structure when the gravitational wave detector on the other side of the material object is connected to a display device. In a preferred embodiment an array of detectors and a gravitational wave lens or lenses can serve to accentuate and concentrate the image of the material object's texture and internal structure. The gravitational waves can also be generated by a celestial background source or sources.
