Abstract:
The paper presents a description of piezoceramic deflectors for optical follow–up systems operating in a turbulent atmosphere and of a high–voltage control block for the deflectors. The sensitivity of a deflector to angular deviations is 1.43•10–6 rad/V–1 and the mechanical resonance frequency is about 1.4 kHz. An efficient high–voltage amplifier is constructed of disconnectable current generators. The output voltage is ±300 V, the frequency transmission band is 0 to 2 kHz at the load capacity of 0.1 mF.
