“…An alternative way to implement a system with improved measurement accuracy, in comparison to systems in which the laser wavelength is tuned to the FBG's central wavelength, is presented in [27] where measurements were carried out on only one FBG slope, which was used as a tilt filter. In this work, a tunable laser source with phase modulation was used, and a tilt filter was used to set a phase mismatch after modulation to implement phase-modulation-to-intensity-modulation conversion.…”

“…The key differences between implementation methods lie in the choice of the physical effect and the resonance type discriminator, which are the basis of IFM implementation. According to the measurement method, there are systems based on a fiber Bragg grating (FBG) [23][24][25][26][27], FBG with a phase shift (PS-FBG) [28][29][30][31], an optical microring resonator (MRR) [32][33][34][35][36], stimulated Brillouin scattering (SBS) [4,[37][38][39][40] and Fano resonance [41].…”

Photonic-assisted receivers for instantaneous microwave frequency measurement are devices used to measure the instantaneous frequency and amplitude of one or more microwave signals in the optical range, typically used in radar systems. Increasingly higher demands are placed on frequency range, accuracy and resolution during the development of instantaneous microwave frequency measurement applications, and these demands can be satisfied by the creation of new devices and operating principles. To permit further development in this area, it is necessary to generalize the experience gained during the development of devices based on frequency and amplitude discriminators of resonance type, including advanced ones with the best performances. Thus, in this report, we provide an overview of all the basic types of approaches used for the realization of photonic-assisted receivers based on fiber Bragg gratings, integrated Fano and optical ring resonators, Brillouin gain spectrum, and so on. The principles of their operation, as well as their associated advantages, disadvantages, and existing solutions to identified problems, are examined in detail. The presented approaches could be of value and interest to those working in the field of microwave photonics and radar systems, as we propose an original method for choosing photonic-assisted receivers appropriate for the characterization of multiple frequency measurements.

“…The frequency of the signal is estimated by measuring microwave power difference [18]. The four-parameter estimation of the sine model is used to estimate both the frequency of sine by the FFT of the sampled signal and the other three parameters according to the frequency in the sine model [19].…”

Abstract-The frequency difference between signal-under-test and reference signal in phase demodulation will affect the result of the actual phase noise measurement. In order to eliminate the effect, an algorithm for both eliminating the frequency difference and extracting the phase noise of the signal-under-test is presented. Simulation and experiment results show that this algorithm is effective. By using the algorithm in our experiment, the noise floor of the measurement system is improved by 10.1 dB and 9.3 dB, respectively, and the measurement precision is improved from 90.03% to 96.31%. In addition, the use of this algorithm can lower the requirement on the frequency precision of reference source and reduce the cost of measurement system.

“…Optical fiber sensors [1][2][3][4][5][6][7][8][9][10][11][12][13] have attracted considerable attention in the past several decades due to their wide applications for a great variety of measurements such as temperature, strain, chemical concentration, refractive index, hydrostatic pressure and their advantages such as small size, light weight, high sensitivity, multiplexing capability, and immunity to electromagnetic interference. Among them, several hydrostatic pressure sensing techniques have been developed, which include hydrostatic pressure sensors based on birefringent fibers [14][15][16], photonic crystal fibers (PCFs) (or microstructured fibers) [17][18][19][20][21][22][23][24], fiber Bragg gratings (FBGs) [18], and Fabry-Pérot interferometers (FPIs) [25][26][27].…”

Abstract-A novel hydrostatic pressure sensor based on a gold-coated fiber modal interferometer (FMI) is proposed and demonstrated. Two single mode fibers (SMFs) are spliced with a lateral offset which forms a single-end FMI. The single-end FMI is gold-coated to enhance the reflectivity and to avoid the influence of any unwanted light from getting into the sensor. Relative reflection spectra of the proposed FMIs with different sensing SMF lengths or different lateral offsets are experimentally investigated. A high hydrostatic pressure sensor test system is proposed for the testing of the proposed FMI pressure sensor. The performance of a gold-coated FMI pressure sensor based on a 12-mm sensing SMF has been experimentally investigated. The proposed pressure sensor has a sensing range from 0 to 42 MPa and a sensitivity of 53 pm/MPa.
