    Abstract: Upstream a microscope objective lens (6), a polarization direction of alight beam is tilted with a first electro-optical deflector (8) between a first polarization direction with which the light beam (3) is deflected by a first polarization beam splitter (28) by a first angle and a second polarization direction with which it is deflected by a second angle. With a second electro-optical deflector (9), the polarization direction of the light beam (3) is tilted between a third polarization direction with which the light beam (3) is deflected by a second polarization beam splitter (28) by a third angle and a fourth polarization direction with which it is deflected by a fourth angle. In a first spatial direction, a second angle difference between the third and fourth angles is about twice a first angle difference between the first and second angles.Arranging the first and second electro- optical deflectors (8, 9) in the beam path of the light beam (3) and rotating the polarization direction of the light beam by means of the first and second electro-optical deflectors (8, 9) are coordinated such that the light beam (3) is tilted about a fixed point (38) in a pupil (39) of the microscope objective lens (6) in the first spatial direction.

    Abstract: A liquid crystal optical device is described configured to provide variable beam steering or refractive Fresnel lens control over light passing through an aperture of the device. The device includes at least one layer of liquid crystal material contained by substrates having alignment layers. An arrangement of electrodes is configured to provide a spatially varying electric field distribution within a number of zones within the liquid crystal layer. The liquid crystal optical device is structured to provide a spatial variation in optical phase delay with a transition at a boundary between zones which is an approximation of a sawtooth waveform across the boundaries of multiple zones. The arrangement of electrodes, device layered geometry and methods of driving the electrodes increase the effective aperture of the overall optical device.
