چکیده
We derive an analytic equation for a ratiometric wavelength measurement system and analyze the influence of the optical source signal bandwidth. Our investigation shows that in a particular optical sensing system, the higher the bandwidth of the optical signal, the better resolution the system will achieve. Experiments based on two types of optical signals (output signal of a tunable laser and a fiber Bragg grating) were carried out, and experimental results verified both the simulation results and the theoretical analysis.

Study of transmission response of edge filters employed in wavelength measurements.
The ratiometric wavelength-measurement system is modeled and an optimal design of transmission response of the employed edge filter is demonstrated in the context of a limited signal-to-noise ratio of the signal source. The corresponding experimental investigation is presented. The impact of the limited signal-to-noise ratio of the signal source on determining the optimal transmission response ...
متن کاملResolution investigation of a ratiometric wavelength measurement system.
Theoretical analysis and experimental investigations are presented on the resolution of a ratiometric wavelength measurement system. Theoretical modeling indicates that the resolution of a ratiometric wavelength measurement system is determined by the signal-to-noise ratio of the input signal and the noise of the photodetectors associated with optical-to-electronic conversion. For experimental ...
متن کاملIncreasing the Accuracy of Blood Hematocrit Measurement by Triplicate Wavelength Photoplethysmography Method
Background and objectives: The importance of continuous monitoring and rapid and accurate informing of changes in blood components (e.g., percentage of hematocrit [HCT]), especially in acute conditions, has motivated researchers to use non-invasive measurement methods. Therefore, this study aimed to evaluate the association between blood HCT and photoplethysmographic signal and the possibility ...
متن کاملA comparison of ratiometric vs. single wavelength measurements in two component systems
The advantages of ratiometric measurements in single dye systems, where the wavelength shifts as a function of a certain parameter (e.g. pH or calcium concentration) are well documented. These include cancellation of variation in the source intensity, scattering and bleaching. However, as will be shown here, many of these advantages are limited only to the context of a single dye system and, in...
