Fiber optic probes provide efficient diagnostic and sensing

Fiber optic probes are used as fiber sensors for minimally invasive measurements into the human body for a long time. To be more precise, an optical fiber sensor is considered to be a special device that allows transforming an input parameter or measurand into another parameter known as the signal. For example, it is possible...

Optical fiber technology is on guard for equipment against laser attacks

An international group of researchers offers a new optical fiber technology in order to safeguard drones, surveillance cameras and other equipment against laser attacks, which can deactivate or break the equipment. This fiber optic technology is known as optical limiting. To be more precise,  optical fiber technology allows telecom switching without the application of electronics....

Fiber optic bundles for position measurements

A traditional optical fiber is used for the transmission of the radiation from the generator to the emitter. Herewith, the emitted radiation operates as a point source and such an optical fiber allows making more precise detection of the position and orientation of the required object. The operation of the fiber optic technology is based...

Endoscopic fiber optic bundle performs self-calibration

Recently a group of scientists from the Dresden University of Technology has presented a developed compact self-calibrating endoscope based on the fiber optic technology that offers to capture 3D images of objects smaller than a single cell. The composition of such an optical fiber endoscope does not include a lens or any optical, electrical, or...

Endoscopic fiber catheter for optical coherence tomography

Usually, a technique for performing an optical biopsy is an invasive one, nevertheless, fiber optic technology has dramatically changed the situation. The new optical fiber technique allows carrying out an optical biopsy without the need to take tissue specimens. Thus, fiber technology has a great influence on the diagnosis and clinical management of numerous diseases....

Raman spectroscopy makes the detection of thyroid lesions easier and faster

Raman spectroscopy is a relatively new fiber optic technology that allows scientists to distinguish between benign and cancerous thyroid lesions in a non-invasive way. The technology of Raman spectroscopy was already demonstrated during the diagnosis of thyroid cancer that took the ninth most commonplace with about 50.000 novel cases diagnosed in the US each year....

Fiber optic bundles perform 3D stereo imaging

The presented fiber optic technology is based on the use of an optical fiber that operates as an independent pixel, thus, allowing coherent fiber optic bundles to transmit more data information than it was possible before (a 2D representation of an image). Nowadays, the spatial light field is able to encode 3D stereo data due to...

Raman spectroscopy vs. FTIR process spectroscopy

Raman spectroscopy is a method of molecular process spectroscopy based on the interaction of light with matter. It allows getting data about the material structure or its characteristics, and in this regard, it is similar to the method of FTIR spectroscopy. Raman process spectroscopy is based on the study of scattered light, while IR spectroscopy...
