Abstract
The right angle geometry between the sound field and the interrogating light wedge suggests that Bragg imaging should be well suited for the study of reflected images. In an effort to improve the intensity and clarity of the reflected images a pulsed dye laser has been developed and tested. Image photographs of various test objects and some anatomical structures were taken and comparisons to earlier transmission mode images were made. Results suggest the possibility that the technique of reflection Bragg imaging can be developed into a viable clinical tool. Efforts have also been directed to improve the optical design for Bragg imaging systems. Those systems previously described in the literature incorporate several optical components which must have dimensions comparable to the desired image size, and, for optimal imaging, these components should also have low f-numbers and be diffraction limited. Alternate lens systems have been studied and designs realized which incorporate large and small cylindrical triplet lenses and prisms. Design specifications for two such systems will be presented.
