摘要： A polarization-insensitive device includes a liquid crystal layer and an adjustment layer that are stacked. The liquid crystal layer is configured to perform, under action of an electric field, first phase adjustment on a passing light component in a first polarization direction. The adjustment layer is configured to obtain a first light beam and a second light beam based on the incident light component in the first polarization direction that passes through the liquid crystal layer, second phase adjustment and polarization direction adjustment are performed on the first light beam at the adjustment layer. A polarization direction of the first light beam is perpendicular to a polarization direction of the first light beam obtained before the polarization direction adjustment; and the first light beam and the second light beam have different propagation directions after passing through the liquid crystal layer.
