Focal Plane Detection in Acoustical Imaging
We present a new configuration for the transmission acoustic microscope using a piezoelectric transducer at the focal plane as the receiver. This configuration appears to be easier to use than the standard twolens system. Examples of images taken in water and liquid nitrogen with this method are presented. The potential of this configuration for nonlinear imaging is also discussed.
