Seeing in Sound: Ultrasonic Imaging with Scanning Acoustic Microscopy

Tune-in to the next installment of Covalent Academy’s Advancements in Instrumentation webinar miniseries to put a finger to the pulse of innovations in Scanning Acoustic Microscopy (SAM).

Guest speaker Lisa Logan from PVA TePla, a global leader in manufacturing acoustic microscopy systems, will describe how acoustic microscopy generates high-resolution 2D and 3D images, and will probe a selection of advanced applications made possible with the vanguard innovations incorporated into contemporary PVA TePla SAM systems.

The event, Seeing in Sound: Ultrasonic Imaging with Scanning Acoustic Microscopy, will air on Thursday, August 20, at 11am PDT.

Ultrasonic frequency sound waves are gentle enough that they are used in medicine to map the faces of unborn children; now, the same underlying technology has been adapted and optimized for fully nondestructive, high-resolution visualization of subsurface features on modern commercial devices. Modern SAM systems from PVA TePla feature high performance pulser-receiver interfaces with a bandwidth of up to 500 MHz: enabling deep signal penetration for complete visualization of buried topographies. Additionally, they are outfitted to enable simultaneous image acquisition through a paired array of 2 transducers (each incorporating its own autofocusing), facilitating numerous imaging modes and a limit resolution below 1 micron.

Learn how different SAM methods can be adapted for use in failure analysis and quality control, as well as process and product development for diverse materials, parts, and devices.


  • Introduce fundamentals of the SAM
  • Break down components and principles of SAM instrumentation
  • Discuss recent advances in SAM instrumentation
  • Explore applications and optimizations for commercial products
  • Flag some common challenges and best practices for SAM operation and analysis

Lisa Logan, as well as a panel of our experts on this subject, will be available to answer questions during a Q&A session at the end of the hour.
