Abstract

Acoustography is the ultrasonic analog of radiography and photography. A unique 2D detector, called acousto-optic (AO) sensor, is used that is capable of directly converting ultrasound into visual images; much like a fluorescent screen is able to convert x-rays into a visual image. The AO sensor offers exceptionally high resolution and can be fabricated to have a large area. This allows image formation through simple shadow casting (analogous to x-ray image formation) or with acoustic lense (analogous to a photographic or video camera). This paper will report on several new developments, which could allow acoustography to provide a simpler more cost-effective alternative to conventional ultrasonic testing.
