Patent ID: 8681412

Claim:
An acousto-optical system comprising: at least one acousto-optical element having at least one transducer that is attached to a crystal receiving input light at an input end and transmitting output light from an output end, the transducer being configured to receive an analog electronic driver signal, generate acoustic waves, and transmit these acoustic waves into the crystal; a driver unit for generating at least one analog electronic driver signal for driving acousto-optical elements modifying light transmitted through the acousto-optical element, said driver unit comprising: a digital data processing unit for generating a digital combination signal, the digital data processing unit comprising: a digital frequency calculation unit for calculating and generating at least 2 initial digital signals, each of the 2 initial digital signals forming the basis for generating particular acoustic frequencies by the transducer; a superposing unit combining the at least 2 initial digital signals into one single digital combination signal; at least one digital-to-analog converter transforming the digital combination signal into an initial analog driver signal; and an amplifier for amplifying the initial analog driver signal to become said analog electronic driver signal.
