Laser Diodes in Sensor Detect Quality Differences in Olive Oils
MADRID, Dec. 26, 2018 — Researchers at the Complutense University of Madrid (UCM) and the Scintillon Institute have designed a sensor that can detect counterfeit olive oil labeled as extra virgin or protected designation of origin. Laser diodes in the sensor detect fluorescence levels, which differ slightly between the adulterated and pure extra virgin olive oils.
Optically Based T-Sensor Could Be Used in Manufacturing, Biomedicine
SÃO PAULO, Jan. 24, 2018 — A temperature-sensor (T-sensor) has been developed that is capable of precisely measuring temperatures in a wide band — between 80 Kelvin (-190 °C) and 750 Kelvin (476 °C). The ultrasensitive sensor, created in the laboratory by researchers at the...
Biomicroscopic System Could Yield More Effective Cancer Treatment
DAEGU, South Korea, Jan. 9, 2017 — A converged biomicroscope based on high frequency ultrasound and optical spectroscopy could overcome the challenges of existing imaging systems for tumor analysis and provide physicians with the means to avoid unwanted outcomes such as cancer...
Fluorescence Spectroscopy: A Powerful Method for Surface Analysis
Nov 30, 2015 — The analysis of technical surfaces is crucial for the optimization of lubrication, coating or cleaning processes, especially with regard to achieving and assuring better quality of final products. Frequently, the essential requirements for an...
New Center Aims to Shape the Future of Manufacturing

BERLIN, Germany, March 23, 2010 — The focus is on semiconductor lasers at this year’s Laser Optics Berlin, held from March 22 to 24, 2010. The Ferdinand-Braun-Institut (FBH) will present the latest developments in laser technology at the event, as well as during the accompanying...
BiOS Hot Topics Lives Up to Its Name
Jan 26, 2009 — In his opening remarks, Sergio Fantini, the moderator of Saturday night’s BiOS Hot Topics session, noted that the evening’s talks represented the state of the art in biomedical optics. And indeed they did. Reflecting a diverse set of interests –...
Tracking Cotton Trash via Fluorescence
Aug 1, 2007 — Cotton producers are plagued with trash -- the bits of leaf, stem, hull, seed coat, bract and other unusable parts of the plant. Such debris determines cotton quality, and cleaner cotton is easier to process into materials such as yarn. Various...
Fluorescence Spectroscopy Identifies Kamut
May 1, 2006 — Kamut, the brand name of a variety of wheat that is believed to have been cultivated in ancient times and that reportedly has a higher nutritional value than traditional wheat, commands a premium price. As a result, there is a desire among suppliers...
Fluorescence Spectroscopy Analyzes Cheese
Mar 1, 2006 — Exposed to too much light and oxygen, cheese can form off-flavors, undergo changes in color and lose nutritional value. Cheese makers and distributors, therefore, search for a combination of product characteristics, storage conditions and packaging...
PLASMONICS
Jul 1, 2005 — Part of the Topics in Fluorescence Spectroscopy series, Radiative Decay Engineering discusses trends, key topics and emerging disciplines in the fields of plasmonics and biophotonics. Targeted to academics, bench scientists and industry...
Spectroscopy Takes Security into the Field
Apr 1, 2004 — With important advances in the miniaturization, cost and performance of optoelectronic devices and sampling accessories, techniques such as fluorescence spectroscopy and laser-induced breakdown spectroscopy have found new applications in...
Hybridizing Spectroscopic Techniques
Feb 1, 2004 — Any given material can be characterized using a wide variety of spectroscopic techniques, each of which provides useful information. Depending on the material in question, of course, some methods are more effective than others. For example,...
