Abstract

High resolution images (90% of Rayleigh limit at all depths) were obtained by computer analysis of digitized signals detected with a 32 element lead zirconium titanate 3. 0 MHz array. The acquisition and storage of all received signals allows subsequent approximate calculation of spatial distributions of such parameters as reflection, index of refraction, attenuation, etc. The extension of these techniques through the use of a fast analog and digital computer interface to obtain real-time and stop-action imaging is treated. Examples of images produced by these algorithms, the time requirements of various algorithms as determined by the computation speeds of present and anticipated digital and analog processing hardware is presented.
