Deflection apparatus for a projection device, a projection device for projecting images, and a method for controlling the deflection unit of the projection device for

摘要

The present invention relates to a deflection system of the projection device for projecting to the observation field Lissajous figure. To produce a Lissajous figure, a deflection unit to also be designed to deflect the beam for deflecting axis of the at least first and second, to produce a vibration on a deflection axis, the polarization unit, the deflection unit generally and a controller having corresponding to the resonant frequency, the operating frequency of the first and second, to generate an actuation signal for the deflection unit has a Q value of 3.000 is less than the deflection unit, wherein The maximum amplitude of the vibration is to remain in the resonance range of the deflection unit, the control unit is designed to control the control frequency of the first and / or second in accordance with the phase position of the measured vibration of the deflection unit was, I and a control circuit. The present invention relates to a method of operating the deflection system and the corresponding projection device with a deflection system such. [Selection Figure 6
