Ultrasonic imaging by acousto-optic interaction in the Raman-Nath regime - Pasteur, J.; Ferriere, R. (Elsevier)
The behaviour of sound imaging systems by diffraction of light is analysed for the Raman-Nath diffraction region. The study is based on a geometrical interpretation of the phenomenon. Imaging relationships are established for plane objects and extended to the 3-D case.
