In this paper, a monolithic polarizing metalens is used to extract multiple polarization information of the target at the same time. The i1maging receiver uses a general detector easily available on the market, which can obtain the intensity information image of multiple polarization components. The polarization measurement speed is fast, and the number of modules in the optical system is reduced The monocular 3D imaging system based on polarization-sensitive metalens collects diffuse reflected light from the surface of the target, and uses different polarimetric sub-images obtained by the metalens to carry out 3D reconstruction of the target.
We theoretically develop a method for maintaining the self-compensated state of a K-Rb21Ne comagnetometer, which is one of the core problems in optimizing the detection sensitivity of the comagnetometer to fundamental interactions and inertial rotation. The result of Rb21Ne coupling dynamics under transverse cosinusoidal magnetic field modulation can present a dispersive response with respect to the varying 21Ne nuclear magnetic field Bn, in which a monotonic interval can be used to monitor the drift of Bn. Furthermore, the result of Rb spin poparization evolution under the constraint of self-compensated-state maintenance exhibits a large enough time scale relative to Rb spin relaxation that it can be regarded as a quasi-static process, thus the adopted time-varying pump light intensity can be obtained using Rb equilibrium polarization. Accordingly, an implementation scheme is given. This method can not only compensate the drifting �", but also promote the system to return back to the original self-compensated state through manipulation of atomic polarization via time-varying pump light, which is useful in stabilizing the system performance.
