摘要： A method and apparatus for actuating an acousto-optical component for manipulating light passing therethrough, in particular for manipulating the illumination and/or detection light in the beam path of a microscope, preferably a laser scanning microscope, where the illumination and/or detection wavelength is adjusted by means of at least one frequency generator connected to the acousto-optical component and controlling the manipulation, the frequency generator generates a signal which generates a spectral spread for the intensity distribution of the wavelength of the illumination and/or detection light for ensuring a temperature-independent manipulation. Actuation is effected by two or more actuation signals in such a way that two or more overlapping and/or superposing main lobes of the transfer function of the acousto-optical component or main maxima are generated.

摘要： A spatial light modulation device includes a phase-modulation type spatial light modulator, a temperature sensor detecting a temperature of the spatial light modulator, and a control unit providing a drive signal to the spatial light modulator. The control unit has a storage unit. The storage unit stores N correction patterns created so as to correspond to N (N is an integer not less than 2) temperature values of the spatial light modulator in order to correct phase distortion of the spatial light modulator. The control unit selects one correction pattern according to a temperature value of the spatial light modulator, and generates the drive signal based on a phase pattern created by adding the one correction pattern to a desired phase pattern. Thereby, it becomes possible to suppress phase distortion according to a temperature change while suppressing a delay in operation.
