Bent Fiber Sensor for Preservative Detection in Milk
Saracoglu, Omer Galip; Hayber, Sekip Esat (MDPI AG, 2016)A fiber optic sensor sensitive to refractive index changes of the outer region of the fiber cladding is presented. The sensor uses bent plastic optical fibers in different bending lengths to increase sensitivity. Measurements ... -
The Experimental Validation of Designed Fiber Optic Pressure Sensors With EPDM Diaphragm
Hayber, Sekip Esat; Aydemir, Umut; Tabaru, Timucin Emre; Saracoglu, Omer Galip (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)This paper focused on the experimental validation of diaphragm-based Fabry-Perot fiber optic pressure sensors (D-FP-FOPS) with ethylene propylene diene terpolymers (EPDM) diaphragm as designed and analyzed sensor tip ... -
Frequency Domain Analysis of Laser and Acoustic Pressure Parameters in Photoacoustic Wave Equation for Acoustic Pressure Sensor Designs
Tabaru, Timucin Emre; Hayber, Sekip Esat; Saracoglu, Omer Galip (OPTICAL SOC KOREA, 2018)A pressure wave created by the photoacoustic effect is affected by the medium and by laser parameters. The effect of these parameters on the generated pressure wave can be seen by solving the photoacoustic wave equation. ... -
A novel approach based on simulation of tunable MEMS diaphragm for extrinsic Fabry-Perot sensors
Hayber, Sekip Esat; Tabaru, Timucin Emre; Saracoglu, Omer Galip (ELSEVIER SCIENCE BV, 2019)A new tunable structure with a Three Leaf Clover (TLC) geometry has been proposed for use in diaphragm-based acoustic pressure sensors. The sensitivity and frequency response of this new structure, which will be an alternative ... -
A Simple, High Sensitive Fiber Optic Microphone Based on Cellulose Triacetate Diaphragm
Hayber, Sekip Esat; Tabaru, Timucin Emre; Keser, Serkan; Saracoglu, Omer Galip (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018)We present a high sensitive fiber-optic microphone (FOM) with a wide measuring range based on a cellulose triacetate diaphragm in this work. The average signal-to-noise ratio (SNR) of the proposed FOM is measured 50.86 dB ... -
Spectral analysis for photoacoustic pressure sensor designs: Theoretical model improvement and experimental validation
Tabaru, Timucin Emre; Hayber, Sekip Esat; Keser, Serkan; Saracoglu, Omer Galip (ELSEVIER SCIENCE SA, 2019)In the pulsed laser photoacoustic (PA) detection and spectroscopy applications, the fundamental frequency of the PA signal produced, and the sensor resonance frequency should be as close as possible to each other so that ...
