Abstract
A method for generating a control signal for an acousto-optical element includes generating a raw signal using at least one correction term by an IQ modulation from a target I component and a target Q component, and amplifying the raw signal to become the control signal. The target I component and/or the target Q component are corrected using the at least one correction term. The at least one correction term is obtained from an analysis of the control signal.
Claims15
A method for generating a control signal for an acousto-optical element, the method comprising:
- generating a digital raw signal using at least one correction term by an IQ modulation from a target I component and a target Q component;
- and
- amplifying the digital raw signal to become the control signal,
- wherein the target I component and/or the target Q component are corrected using the at least one correction term, and
- wherein the at least one correction term is obtained from an analysis of the control signal.
A method for generating a control signal for an acousto-optical element, the method comprising:
- pre-distorting a raw signal by a correction function;
- and
- amplifying the raw signal to become a triggering signal according to a transfer function,
- wherein the correction function is obtained by amplifying a reference signal according to the transfer function to become an amplified reference signal, wherein the transfer function is approximated as a polynomial with coefficients, and the amplified reference signal is compared with the reference signal.
