High sensitivity relative humidity sensor based on two parallel-connected Fabry-Perot interferometers and Vernier effect

Yuan Wang et al.

Summary: In this study, a highly sensitive relative humidity sensor based on two Fabry-Perot interferometers in parallel with the Vernier effect was designed and demonstrated. The sensor showed improved sensitivity due to the Vernier effect. Experimental results showed that the RH sensitivity of the sensor is up to -586.6 pm/% RH, which is 17.3 times that of a single FPI sensor without the Vernier effect. The sensor also possessed the advantages of simple manufacturing, robust structure, and stable operation.

A single-film fiber optical sensor for simultaneous measurement of carbon dioxide and relative humidity

LiangLiang Liu et al.

Summary: Colorimetric measurement is an important method for bio/chemical sensing, especially in biomedical applications. This study presents a novel optical fiber sensor that combines colorimetric measurement and a white light Fabry-Perot interferometer for simultaneous measurement of CO2 and RH, with negligible cross-sensitivity. The sensor demonstrates reversible response to CO2 and RH, with a sensitivity of approximately 0.19 nm/%RH for RH measurement and a polynomial correlation for CO2 concentration.

Vernier Effect-Based Optical Fiber Sensor for Humidity and Temperature Monitoring

Ricardo Ferreira et al.

Summary: This study presents a simple and cost-effective sensing scheme for humidity and temperature sensing, utilizing the optical Vernier effect with two different fiber optic Fabry-Perot interferometers. By using an insensitive reference FFPI and a sensitive FFPI, the complexity associated with traditional isolation schemes was mitigated, resulting in high sensitivities.

Fiber Optic Sensor for Simultaneous Measurement of Refractive Index and Temperature Based on Internal-and-External-Cavity Fabry-Prot Interferometer Configuration

Cheng Zhou et al.

Summary: A crosstalk-free fiber optic sensor for simultaneous measurement of refractive index (RI) and temperature was proposed and experimentally demonstrated based on an internal-and-external-cavity Fabry-Perot interferometer (IECFPI) model. The sensor utilizes silica and open cavities in its design, and achieves high sensitivity for both RI and temperature measurements by monitoring wavelength shifts. Experimental results showed promising RI and temperature sensitivities, making the sensor a potential candidate for applications in the food industry and environment monitoring.

Optical Vernier Effect: Recent Advances and Developments

Andre D. Gomes et al.

Summary: The optical Vernier effect enhances sensitivity and resolution of fiber sensors by generating magnified sensing capabilities in the output spectrum. This effect relies on the overlap between signals of two slightly detuned interferometers, leading to a new generation of highly sensitive sensing devices.
