摘要： An optical head (10) using a variable optical component (10), which component comprises bendable nano-elements (3) that can be switched between a bent and non-bent state by means of a driver-field applied between electrodes (1, 2). In the bent state the nano-elements absorb radiation and therefore adapt the radiation intensity distribution of the radiation beam passing the component.

摘要： An optical diffraction element (1) comprises a diffraction layer (4) which is divided into diffraction strips (6) alternating with intermediate strips (8). The diffraction strips comprise nano-elements (10) which are aligned in one direction and absorb radiation (b) which is linearly polarized in this direction. The diffraction element may be a linear or two-dimensional grating (1) or a Fresnel lens (160). The polarization-sensitive grating can be used in optical systems in which only radiation with a specific polarization direction should be diffracted, or in an optical record carrier to allow reading of an information structure with high spatial frequencies.

摘要： A transducer device for detecting an environmental state within a biological material including a channel comprising a fluid, a hydrogel material, which is adapted to change its volume when getting into contact with an environmental material and/or when detecting an environmental change, and which is mechanically coupled to the channel such that the volume of the channel changes when the volume of the hydrogel material changes. The transducer device further includes a sensor, which is adapted to generate a signal upon detection of the change of a physical property of the fluid that is induced by the volume change of the channel. By applying the transducer device, an accurate monitoring of physiological parameters, for which the hydrogel material is sensitive is possible. It is also possible to apply the transducer device outside of the bodily lumen, for example to monitor the blood of a patient outside the bodily lumen.

摘要： Disclosed are systems and methods for providing multi-channel illumination. A reflector and at least four solid state light sources are operable to emit light. A plurality of combinations of the solid state light sources are identified, where each of the combinations is operable to emit light that matches a target color point. The combinations are ranked based on their respective luminous flux value, and at least one of the combinations is selected based on the rank. A duty cycle of a control signal of each light source of the selected combinations is determined to control light emitted from the reflector.

摘要： The invention relates to a method and a device for driving an LED string of a first LED segment (11) and at least one further LED segment (12, 13, 14) connected in series. Each LED segment has at least one light emitting diode, LED. The LED string is powered by a rectified AC mains voltage. The first LED segment (11) is powered when the rectified AC mains voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC mains voltage is above a second voltage level higher than the first voltage level. The first LED segment emits light having a first color temperature, and the further LED segment emits light having a second color temperature higher than the first color temperature. The light emitted by the first LED segment and the light emitted by the further LED segment are superimposed. The color temperature change of the light emitted by the LED string, when dimmed, resembles the color temperature change of an incandescent lamp.
