Abstract

We have built a Bragg imaging system using carefully designed cylindrical and spherical lenses essentially free of spherical aberrations. We are particularly interested in applying the system to medical applications and have therefore restricted ourselves to low frequencies of ultrasound (1–5 MHz). The system has been used to obtain transmitted and reflected images. In addition to images, quantitative data on the light intensity in the image as a function of sound intensity have been obtained, Engineering data on the optical mounting and transducer are also discussed.

The experience gained so far leads us ti believe that a well designed system will yield useful medical images.
