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.

Microscope having a freely programmable laser pulse sequence, and corresponding method

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.

Method and signal generator for controlling an acousto-optical element, microscope with an arrangement comprising the signal generator and an acousto-optical element

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.

A circuit for controlling a microscope using a controller includes a slow memory configured to store control information. The controller is configured to control microscope parameters based on the control information. The circuit includes a data loader and at least two fast memories. The data loader is configured such that control information is written from the slow memory alternately into one of the at least two fast memories. The circuit also includes a multiplexer configured to permit access by the controller to one of the at least two fast memories in alternating fashion so as to read control information. The data loader is configured to control the multiplexer in such a way that a write operation by the data loader and a read operation by the controller will not occur simultaneously on the same fast memory.

Circuit and method for controlling a microscope

A circuit is configured to generate periodic control signals including at least two mutually phase-shifted control signals. The circuit includes a plurality of generator circuits, where a separate generator circuit is provided for each control signal output by the circuit. Each generator circuit includes a phase value memory configured to store a phase value, where the phase value defines a phase shift. Each generator circuit includes an activation input and, in response to application of an activation level to the activation input, is configured to initiate a generation of a control signal which is phase-shifted by an amount defined by the phase value. The activation inputs of the generator circuits are connected together to an activation circuit for outputting an activation level to the generator circuits simultaneously.

A circuit for delaying an input signal includes first and second delay units. The input signal is switched to the first delay unit which is configured to delay the input signal by k cycles of a first clock signal so as to generate a value xand transfer the input signal to the second delay unit. The second delay unit includes a converter and a second shift register. The converter is connected to the second shift register by n leads. The value xand a value xare present at the converter, where xis the input signal delayed by k&#x2212;1 cycles of the first clock signal, The converter is configured such that the value xis present on leads 1 to m and the value xis present on leads m+1 to n. The second shift register is configured to successively output values present on leads 1 to n.
