WASHINGTON -- In an important step toward endoscopic diagnosis of cancer, researchers have developed a handheld fiber optic probe that can be used to perform multiple nonlinear imaging techniques ...

Accurate diagnosis of cancer typically requires removal of a tissue sample for analysis, but optical alternatives to these biopsy procedures would be faster, less invasive and potentially more precise ...

The basics of fiber optic cables and bundles and how they can be used to collect and direct light are discussed in ‘An Introduction to a Spectrometer: Fiber Optic Bundles’. This article will discuss ...

At its core, SPM operates on the principle of measuring interactions between a sharp probe and the surface of a material. As the probe scans across the surface, it detects variations in physical ...

Scanning probe microscopy is used to create images of nanoscale surfaces and structures or manipulate atoms to move them in specific patterns. It involves a physical probe that scans over the surface ...

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 ...

NIST engineers measure the diameter of tiny holes by imaging the shadow of a microsphere tipped fiber. US technology and standards agency NIST thinks its fiber deflection probe could be ideal for ...
