A Single Point, Multi-Parameter, Fiber Optic Sensor Based on a Combination of Interferometry and LSPR
Muri, Harald Ian; Bano, Andon; Hjelme, Dag Roar (Journal article; Peer reviewed, 2018)We demonstrate a new single point, multi-parameter, fiber optic sensor concept based on a combination of interferometric and plasmonic sensor modalities on an optical fiber end face. The sensor consists of an extrinsic ... -
Classification of municipal solid waste using deep convolutional neural network model applied to multispectral images
Muri, Harald Ian; Hjelme, Dag Roar (Peer reviewed; Journal article, 2021)Minimization of the environmental impact of the incineration process and to produce energy efficiently are the most important considerations in obtaining efficient operation of waste-to-energy (WtE) plants. WtE operation ... -
Dual parameter fiber optic sensor combining a Fabry-Perot and a Mach-Zehnder interferometer
Hammarling, Krister; Wahl, Markus Solberg; Muri, Harald Ian; Engholm, Magnus; Hjelme, Dag Roar (Journal article, 2017)A new concept for dual parameter fiber optic sensor has been developed and characterized, both in a two-fiber and single-fiber configuration. The liquid sensor measures ethanol concentration with a stimuli responsive ... -
First step towards an interferometric and localized surface plasmon fiber optic sensor
Muri, Harald Ian; Bano, Andon; Hjelme, Dag Roar (Journal article; Peer reviewed, 2017)We present a first demonstration of a novel multi-parameter fiber optic (FO) sensor concept based on gold nanoparticles (GNP) embedded in a stimuli-responsive hydrogel material. A hemispherical hydrogel immobilized on the ... -
The Importance of Optical Fibres for Internal Temperature Sensing in Lithium-ion Batteries during Operation
Wahl, Markus Solberg; Spitthoff, Lena; Muri, Harald Ian; Jinasena, Asanthi; Burheim, Odne Stokke; Lamb, Jacob Joseph (Journal article; Peer reviewed, 2021) -
LSPR and Interferometric Sensor Modalities Combined Using a Double-Clad Optical Fiber
Muri, Harald Ian; Bano, Andon; Hjelme, Dag Roar (Journal article; Peer reviewed, 2018)We report on characterization of an optical fiber-based multi-parameter sensor concept combining localized surface plasmon resonance (LSPR) signal and interferometric sensing using a double-clad optical fiber. The sensor ... -
LSPR Coupling and Distribution of Interparticle Distances between Nanoparticles in Hydrogel on Optical Fiber End Face
Muri, Harald Ian; Hjelme, Dag Roar (Journal article; Peer reviewed, 2017)We report on a new localized surface plasmon resonance (LSPR)-based optical fiber (OF) architecture with a potential in sensor applications. The LSPR-OF system is fabricated by immobilizing gold nanoparticles (GNPs) in a ... -
Mapping nanoparticles in hydrogels: A comparison of preparation methods for electron microscopy
Muri, Harald Ian; Hoang, Linh; Hjelme, Dag Roar (Journal article; Peer reviewed, 2018)The distribution of noble metal nanoparticles (NMNPs) in hydrogels influences their nanoplasmonic response and signals used for biosensor purposes. By controlling the particle distribution in NMNP-nanocomposite hydrogels, ... -
Metodologi for synkronisering av hyperspektral klassifisering med sorteringsmaskiner
Mørenskog, Erik Rundhovde (Master thesis, 2020)Hyperspektral avbildning har vist seg å være et nyttig verktøy for fjernmåling i laboratorie-, felt-, luftbårne og industrielle applikasjoner. Teknikken gir høy spektral oppløsning i det synlige og infrarøde spekteret, som ... -
Reflectance of microwaves and millimetre waves in homogeneous and heterogeneous media with moisture and metal contents
Hilde, Oscar (Master thesis, 2021)Denne masteroppgaven tar for seg mikrobølge og millimeterbølge interaksjon med jernpartikler og svamper som inneholder vann. Drude-modellen ble brukt til å beregne brytningsindeksen til jern for bølgelengder opp til 286 ... -
Sensor Technology Options for Municipal Solid Waste Characterization for Optimal Operation of Waste-to-Energy Plants
Muri, Harald Ian; Hjelme, Dag Roar (Peer reviewed; Journal article, 2021)Reuse, refurbishing, and recycling are the most sustainable options for handling waste materials. However, for municipal solid waste (MSW) that is highly heterogenic, crude, contaminated, and decrepit, thermal conversion ...
