* - the blade has 100 slots on external circle and 2 slots – on internal one. The frequency is stabilized on external circle (high frequency), but optical beam is chopped on internal one (low frequency). The phase shift range is from -180° to +180° according to the high frequency (on external circle).
** - the optical aperture with a 100-slot blade is 1.5 mm
