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:
The examples relate to various implementations of a software configurable luminaire and a transparent display device for use in such a luminaire. The luminaire is able to generate light sufficient to provide general illumination of a space in which the luminaire is installed and provide an image display. The general illumination is provided by additional light sources and/or improved display components of the transparent display device.
Abstract:
The examples relate to various implementations of a software configurable lighting device, installed as a panel, that offers the capability to appear like and emulate a variety of different lighting devices. Emulation includes the appearance of the lighting device as installed in the wall or ceiling, possibly, both when lighting and when not lighting, as well as light output distribution, e.g. direction and/or beam shape.
Abstract:
An optical component (42) for coupling out an individual output beam (10 i ) from a collective output beam (8) comprises a plurality of radiation-reflecting regions (43 i ) which are grouped in such a way that regions (43 i ) of the same group (i) serve for guiding different partial beams (12 i ) of the individual output beam (10 i ) to the same scanner (3 i ).
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.
