Abstract: A method for suppressing a spurious pulse following a measurement pulse in a measurement signal using a circuit includes generating a square-wave signal from the measurement signal. A delayed square-wave signal is generated by delaying the square-wave signal by a time span τ1. The delayed square-wave signal is input into a control input of a switching arrangement. The measurement signal or a signal derived therefrom is input into an input of the switching arrangement. The signal at the input of the switching arrangement is switched to a first output of the switching arrangement based on the delayed first square-wave signal at the control input of the switching arrangement. The time span τ1 is matched to the measurement signal such that the switching arrangement is not switched to the first output during the spurious pulse. A signal at the first output is output as an output signal of the circuit.

Abstract: A microscope includes an illumination system configured to illuminate a sample chamber with laser pulses. The illumination system includes a control device with stored, modifiable illumination parameters, with trigger outputs, to which at least one externally triggerable laser system is connectable in each case, and with a trigger generator configured to produce temporally successive trigger signals for triggering the at least one laser system. The microscope is configured such that an assignment of the trigger signals to the trigger outputs and/or a time interval between successive ones of the trigger signals depends on the illumination parameters.

Abstract: An electric circuit for driving an acousto-optic crystal includes a piezoelectric converter configured to drive the acousto-optic crystal to vibrate mechanically. A signaling cable is configured to conduct a first electrical alternating-current signal and a second electrical signal. The electric circuit further includes a first frequency-separating filter and a second frequency-separating filter, each of the frequency-separating filters having an input, a high-frequency output and a low-frequency output. The input of the first frequency-separating filter and the input of the second frequency-separating filter is connected to the signaling cable, and the high-frequency output of the second frequency-separating filter is connected to the piezoelectric converter.

Abstract: A method for generating a control signal, having at least one frequency component, for an acousto-optical element, from one frequency spectrum having the at least one frequency, or from multiple frequency spectra which together have the at least one frequency, includes the step of obtaining, from the one frequency spectrum or from the multiple frequency spectra, one transmit signal in the time domain in each case via an inverse Fourier transform. The one or the multiple transmit signals are modulated via a single-sideband modulation onto a carrier signal having a carrier frequency in order to obtain one modulated signal in each case. The control signal is obtained as a real part of the one modulated signal or as a consolidation of the real parts of the multiple modulated signals.

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.
