Automatic optical failure detection on large ultrasonic arrays

The search for improved resolution in super-resolution ultrasound (SRUS) imaging leads to larger ultrasound arrays and smaller elements. A current large row-column addressed (RCA) array spans $\approx 21\times 21\ \text{mm}^{2}$ with $190 +190$ elements separated by a kerf of $3\ \mu\mathrm{m}$. Increasing array dimensions and decreasing feature sizes not only make...
