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.

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 light/voltage converter circuit for converting intensity fluctuations of light into an alternating voltage measurement signal includes a photodiode configured to detect the light and a transformer comprising a primary coil and a secondary coil. The primary coil is connected in a series circuit to the photodiode, and the alternating voltage measurement signal is applied to the secondary coil. An electrical network is configured to block direct current and conduct alternating current. The electrical network is connected in parallel with the series circuit consisting of the primary coil of the transformer and the photodiode.

Abstract: A detector device is designed to capture light and to generate electrical signals. The detector device includes a housing and a detector disposed in the housing so as to be moveable at least partially in the housing and with respect to the housing. The detector device is useable in a detection system and/or in a microscope.
