We describe the theory and practical implementation of an iterative computer algorithm (an extension of the Gerchberg Saxton algorithm, originally developed for electron microscopy) for enabling an estimate of the complex reflectance function of a material to be reconstructed from measured values of only the magnitude of the response of an acoustic microscope (i.e. without the phase of the transducer voltage). Results are presented for eight materials measured with a spherical lens (at 320 MHz) and five with a cylindrical line‐focus lens (at 210 and 228 MHz). 1989 Blackwell Science Ltd
