Medical optical fibers facilitate disease diagnosis

Optical fiber is very often used in medicine in the field of diagnostics. Since optical fibers can be very thin and can be twisted into flexible strands, they can be applied in the examination of blood vessels, lungs, and other human organs. Optical fibers allow doctors to perform visual analysis and treatment of various diseases...

The full overview of fiber optic bundles applied in medicine

A fiber optic bundle is an element of a fiber cable that is a very thin quartz thread with a diameter of 0.1 mm. This optical fiber is used for transmitting electromagnetic radiation. The operating principle of the fiber bundle is based on the use of such processes as reflection, as well as refraction of...

Optical fibers that promote medicine

Medical devices for direct observation of internal organs, sensors for reliable blood analysis, and laser systems for internal surgery — all these tools are based on the technology of optical fibers. To be more precise, inserting optical fibers into natural holes or small incisions and passing them through channels in the human body allow doctors...

Optical fibers act as a monitoring tool

Researchers from Switzerland have developed a new glacier monitoring tool based on fiber optic technology. These optical fibers allow monitoring the entire glaciers. The thing is that seismic monitoring coverage of glaciers is considered to be inexact because of current seismometers’ challenge being mounted in glacial areas. The developed fiber optic system has been already...

Hollow optical fibers increase polarization purity

Saving laser beam light in a pure polarization state plays a crucial role in interferometry to provide super accurate measurements of length, time, or other quantities. Optical fibers allow performing it, however, now the light is necessary to be directed through a vacuum for gold-standard purity that is considered to be too expensive and even...

Fiber optic cables: types and characteristics

Fiber optic cable is a fundamentally different type compared to other types of cables. Its information is transmitted by a light signal. Its main element is a transparent optical fiber, through which light travels for huge distances (up to tens of kilometers) with a slight attenuation. The structure of this fiber cable is very simple...

Optical fibers overcome the limits of Rayleigh backscattering

Fiber optic technology is considered to be ideal for distributed sensing applications. Optical fibers of more than 1 km length are actively used in fiber optic cables, therefore, they allow obtaining data about temperature, strain, and acoustics without need for electrical connections, herewith, optical fibers have resistance to harsh environmental conditions in different structures. It...

Fiber optic probe for high-resolution fluorescence imaging

Fiber optic probes with targeted multispectral and spatiotemporal illumination properties for imaging processes finds new applications in numerous diagnostic biomedical studies. Nevertheless, these fiber optic systems are mostly adapted in standard microscopes, therefore, limiting their use for in vitro applications. Recently t a team of researchers has presented new optical fiber technology based on a...
