Abstract
A prototype of a digital control system based on VME busArchitecture that is able to perform the automatic control of optical res- onators (Fabry-Perot cavites, Michelson Interferometers, etc..), has beenbuilt in Napoli, to ascertain the feasibility of the digital control techniquein the alignment of the mirrors of the Virgo Antenna, the italian-frenchproject of a very long baseline interferometric antenna for GravitationalWaves Detection. Its main features are the controlled band (0 -i- 5 KHz),12 and 16 bit ADC/DAC with a sampling rate of 40 kHz, error signal ex- traction by means of synchronous demodulation.
