Sensors | Free Full-Text | Recent Advances in Gas and ...

Recently, the Vernier effect has been proved to be very efficient for significantly improving the sensitivity and the limit of detection (LOD) of chemical, biochemical and gas photonic sensors. In this paper a review of compact and efficient photonic sensors based on the Vernier effect is presented. The most relevant results of several theoretical and experimental works are reported, and the ...

Highly Sensitive Airflow Sensor Based on Fabry–Perot ...

· A novel highly sensitive airflow sensor based on Fabry-Perot interferometer (FPI) and Vernier effect is proposed and demonstrated. The sensor is fabricated by splicing a section of hollow-core fiber (HCF) between a lead-in single mode fiber (SMF) and a section of SMF, which is almost one-fifteenth the length of the HCF. Airflow changes the cavity length of the FPI, which leads to the shift of ...

CO2 Gas Sensor User Manual – Vernier

The Vernier CO 2 Gas Sensor measures gaseous carbon dioxide levels in the range of 0 to 10,000 ppm (Low range setting) or 0 to 100,000 ppm (High range setting) by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. Carbon dioxide gas moves in and out of the sensor tube by diffusion through the twenty vent holes in the sensor tube. The sensor uses a small …

Gas Pressure Sensor - Vernier

The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

We propose and demonstrate a simple highly-sensitive gas pressure sensor based on harmonic Vernier effect. By fusion splicing two hollow silica capillaries, a cascaded Fabry-Perot (FP) cavity is formed. Without special photonics crystal fibers or laser machining involved, the fabrication process is greatly simplified. The interplay between the two interferometers consisting the FP cavity leads ...
