Problems solved by technology

However, each polarization state in this method only corresponds to a small piece of interference information, which greatly reduces the spectral resolution of the device.

At the same time, there is aliasing phenomenon in the interference information of adjacent Stokes components, which further reduces the spectral resolution of the device, and even affects the accuracy of the restored spectrum. Moreover, the structure of the static all-optical modulation module is complex and the production cost is high.
