“…Because the system uses multiple cameras and contains multiple light splitters and polarization devices, the volume of the fractional amplitude imaging system is usually large. In 2016, Ben et al proposed a system model using polarization beam splitter instead of polarizer [72]; as shown in Figure 10a, the root mean square error of this model is about 0.026 • , and the average absolute error is 0.02 • . In addition, they put forward a calibration algorithm.…”

A polarized light sensor is applied to the front-end detection of a biomimetic polarized light navigation system, which is an important part of analyzing the atmospheric polarization mode and realizing biomimetic polarized light navigation, having received extensive attention in recent years. In this paper, biomimetic polarized light navigation in nature, the mechanism of polarized light navigation, point source sensor, imaging sensor, and a sensor based on micro nano machining technology are compared and analyzed, which provides a basis for the optimal selection of different polarized light sensors. The comparison results show that the point source sensor can be divided into basic point source sensor with simple structure and a point source sensor applied to integrated navigation. The imaging sensor can be divided into a simple time-sharing imaging sensor, a real-time amplitude splitting sensor that can detect images of multi-directional polarization angles, a real-time aperture splitting sensor that uses a light field camera, and a real-time focal plane light splitting sensor with high integration. In recent years, with the development of micro and nano machining technology, polarized light sensors are developing towards miniaturization and integration. In view of this, this paper also summarizes the latest progress of polarized light sensors based on micro and nano machining technology. Finally, this paper summarizes the possible future prospects and current challenges of polarized light sensor design, providing a reference for the feasibility selection of different polarized light sensors.

Polarization light has been used as a key navigation cue by many animals under a stable celestial polarization pattern. Inspired by animals' unrivaled navigation skill, a bionic polarization sensor is designed previously to obtain the angle of polarization and degree of polarization. However, the accuracy and stability of the sensor are restricted by multi-source errors. In order to improve the accuracy of the sensor, in this paper, the multi-source errors are analyzed and modeled. A coarse calibration is presented to reduce the effect of inconsistency and interference. In addition, the extended Kalman filter and the unscented Kalman filter are designed to estimate the multi-source error or interference and compensate for the bionic polarization sensor. Finally, simulation and indoor experiments are conducted to validate the effectiveness of the proposed calibration method.INDEX TERMS Multi-source error, sensor calibration, extended Kalman filter, unscented Kalman filter.

In the magnetic fields built by neodymium–iron–boron (NdFeB) permanent magnets, the corresponding relationship among the concentration of sodium chloride solution, glucose solution and their magnetic rotation angles was researched in the temperature range 20–24°C. A helium–neon (He–Ne) laser with a wavelength of 632.8 nm was used in the experiment as light source. A new device is designed for assembling and adjusting the NdFeB permanent magnets. The permanent magnets have no thermal effect compared to an energized solenoid. The corresponding relationship between the concentration and rotation angle is calibrated by standard concentration gradient solutions. Then the concentration can be detected by using this relationship. The rotation angle of the solution is proportional to the concentration and increased with an increase of the magnetic induction intensity. In the magnetic cavity with Φ12 mm dimension, the rotation angles of sodium chloride solutions in the range 0–30 g/100 ml vary from 2.66° to 3.73° and their relative errors range from −1.39% to 1.34%. The rotation angles of glucose solutions in the range 0–50 g/100 ml vary from 2.66° to 26. 44° and their relative errors range from −0.55% to 1.00%. The uncertainty of this system is 0. 05°.
