A photograph of the spherically polished end of an aluminum rod that was used as the backing substrate for the transducers.
Scanning electron microscopy images of the ZnO film on the aluminum (Al) backing. The first image (a) shows the curvature of the Al backing and the second image (b) is a close-up view of the ZnO film.
Measured pulse-echo waveform (solid line) and spectrum (dashed line) for transducer 2.
Wire target image acquired with transducer 1 (a), as well as the two-way axial (b) and lateral (c) line spread functions.
Zebrafish eye image aquired using transducer 1. The cornea (C) and iris (I) are visible in this image.
Zebrafish eye image aquired using the transducer 1 that clearly shows the inner and outer surfaces of the cornea (arrows).
Measured transducer performance whereby CF is the center frequency, BW is the bandwidth, IL is the insertion loss, and PL is the pulse length.
