“…However, there is the dynamic of the process, there are values with greater convergence rate than this bound. The mean measurement frequency is calculated using (6) and the perceptual relative error is calculated with (10) The results of the calculation of (10) for all the above mentioned cases (combinations of all possible revised values of 3 reference and 4 unknown frequencies) are shown in Table I. It is shown that using a standard 1 MHz the relative error is less than the limit for the appropriate relative error for the application.…”

In this paper, a novel method of frequency counting of signals coming from automotive sensors is presented. The present method helps to improve fast resolution of output parameters of typical automotive frequency-domain sensors (FDS). Controlling the electromechanical systems in today's cars is a task that requires a high processing speed. The method proposed here has been tested under computer experiments, and theoretical results have shown that it meets the requirements of speed of response and offset error of the parameters under measurement. Here, both a principle of rational approximation and its application to fast registration of frequency changes in the signal that is proportional to the physical parameter under measurement are shown. Finally, some experimental results are shown as well.Index Terms-Frequency domain sensors, frequency measurement, rational approximation.

Due to its closed-loop structure, the silicon microring resonator can have a very high quality factor value and its output intensity is very sensitive to different wavelengths. These characters, plus the potential in CMOS compatible fabrication process, are making the silicon microring resonator a key building block of photonic integrated circuits for the applications of filtering, switching, modulation, and wavelength conversion. In parallel, the silicon microring resonator has also been proposed as a compact and highly sensitive optical sensor. In recent years, microring sensing related research and development has been growing consistently and rapidly for the purposes of environment monitoring, health diagnosis, and drug development. This article will firstly review the recent development in silicon microring sensors, which are mainly concentrated in two areas: to improve the sensitivity and to enhance selectivity. In order to have better understanding of this class of sensors, the basic structure of the microring sensors, its working principle, and its unique properties will be described. Then, our own works, in particular, the methods to improve dynamic range, sensitivity, and stability of the silicon microring sensors, will be presented. By studying the fundamental optical properties of the coupled microring resonators, novel silicon microring sensors with better and more reliable sensing performance are constructed. Finally, through studying the interactions between chemistry and optics, acceleration and optics, the specific applications in glucose sensing and seismic sensing are discussed.

We propose a novel high-performance digital optical sensor based on the Mach-Zehnder interferential effect and the dual-microring resonators with the waveguide-coupled feedback. The simulation results show that the sensitivity of the sensor can be orders of magnitude higher than that of a conventional sensor, and high quality factor is not critical in it. Moreover, by optimizing the length of the feedback waveguide to be equal to the perimeter of the ring, the measurement range of the proposed sensor is twice as much as that of the conventional sensor in the weak coupling case.
