Tissue elasticity can be detected using a scanning acoustic microscope (SAM), whereby acoustic images are created from the speed of sound through tissues. This system discriminated pulmonary tissue ...

Most automated quality inspection technologies involve machine vision systems and, increasingly, aspects of artificial intelligence-powered software to speed the identification of part defects. But ...

For the best results with SAM systems, pay close attention to both the digitizer characteristics and the signal path. Automated inspection techniques are widely used in the semiconductor industry for ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

Traditional ultrasonic imaging systems usually transmit broadband ultrasonic pulses through the full sample volume under study. By analyzing these pulses, researchers can measure sample thickness, ...

Microscopes are of three basic types: optical, electron (or ion), and scanning probe. The modern optical or light microscope was developed in the mid-19th century. Optical microscopes use transparent ...

The demonstration relies on a quantum-mechanical effect known as inelastic tunnelling. (Courtesy: A Weismann/Christian-Albrecht University of Kiel) The sensitivity of a scanning-tunnelling microscope ...

Ultrasound’s sensitivity to material interfaces makes it useful in screening plastic-encapsulated microcircuits (PEMS) and other components used in the assembly of medical electronics products. The ...
