Guest speaker Lisa Logan from[**PVA TePla**](https://www.pvatepla-sam.com/en/), 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. ## This Webinar Will: - 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. ## Subsurface Imaging Enabled by Sound Waves 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](https://covalent.com/solutions/failure-analysis/) and quality control, as well as process and product development for diverse materials, parts, and devices.
