The schematic diagram (see
based on the reflection-coupled principle with 4 periods per revolution and a maximum speed
of 30000 rpm. The separation of the coupler from the rotating aperture should be about
approximately 1 mm. In the schematic diagram, the power supply for the coupler was provided
externally because of the relatively high current consumption.
