Compact motorized circular wheel of polarization optics for ultra-broadband polarization state generation

A novel filter wheel for multi-channel switching and polarization rotation

“…Fig. 1(a) and 1(b) present the previous and the last schematic illustration of the proposed mechanism respectively, which includes a drive motor, a drive shaft, two unidirectional bearings (UDBs), a plate body, and a drive wheel [16]. The drive motor provides movement in the clockwise as well as counterclockwise directions.…”
