摘要： A variable focus lens comprising a first fluid (A) and a second, non-miscible, fluid (B) in contact over a meniscus. A first electrode (2) separated from the fluid bodies by a fluid contact layer (10), and a second electrode (12) in contact with the first fluid to cause an electrowetting effect whereby the shape of the meniscus is altered. The fluid contact layer has a substantially cylindrical inner wall.

摘要： A switchable optical element has a fluid chamber including immiscible first and second bodies of fluid disposed relative to one another along an optical axis of the element. The second body of fluid is movable in a direction away from the optical axis (A) by electro-wetting action, giving the switchable optical element a changeable transmissivity along the optical axis.

摘要： A zoom lens comprising, from the object side to the image side, a front lens group (72), a controllable lens group, and a rear lens group (74), the controllable lens group comprising a voltage-controlled electrowetting device, which device contains a first fluid (A) and a second fluid (B) having different refractive indices, with at least two first fluid-second fluid interfaces (40,42). The curvatures, and thus the lens power, of these interfaces can be changed independently by supplying a voltage (V1, V2) to electrodes (22,32) of the device, so that no mechanical movement of lens elements is needed.

摘要： A method for providing information about a spatial gain distribution of a scintillator for a primary radiation is provided which does not require the irradiation of the scintillator with the primary radiation. The method comprises the step of irradiating the scintillator with a secondary radiation for generating an image of a spatial secondary gain distribution of the scintillator for said second radiation. The spatial secondary gain distribution image corresponds to an image of the spatial primary gain distribution for the primary radiation. In an embodiment of the invention, i.e. in an X-ray imaging device where the primary radiation is X-ray radiation, the invention provides for an accurate calibration of the X-ray detector without irradiating the X-ray detector with X-ray radiation. Rather, irradiation with UV radiation as the secondary radiation provides the desired spatial secondary gain distribution image which can be used for calibration.
摘要翻译：提供了一种用于提供关于主辐射的闪烁体的空间增益分布的信息的方法，其不需要用初级辐射照射闪烁体。该方法包括用二次辐射照射闪烁体的步骤，用于产生用于所述第二辐射的闪烁体的空间二次增益分布的图像。空间二次增益分布图像对应于初级辐射的空间初级增益分布的图像。在本发明的一个实施例中，即在主要辐射是X射线辐射的X射线成像装置中，本发明提供了对X射线检测器的精确校准，而不用X射线辐射照射X射线检测器。相反，用UV辐射作为辅助辐射的照射提供了可用于校准的期望的空间二次增益分布图像。

摘要： It is described a method for measuring the sharpness in an X-ray system (100). The measurement is based on a common edge response. An edge device (120) representing the projection device is placed within a beam-shaping device (470). Due to a high geometrical magnification factor the edge response function (241a) and also both an impulse response function (246a) and a modulation transfer function (251a) will predominately depend on the size of the focal spot (112) rather than on a pre-sampling spread function of a detector (130) being used for receiving the X-radiation (117), which has laterally passed the edge device (120).
摘要翻译：描述了用于测量X射线系统（100）中的锐度的方法。测量基于公共边缘响应。表示投影装置的边缘装置（120）被放置在光束成形装置（470）内。由于高几何放大因子，边缘响应函数（241a）以及脉冲响应函数（246a）和调制传递函数（251a）都将主要依赖于焦点（112）的大小而不是预先用于接收横向通过边缘装置（120）的X射线（117）的检测器（130）的取样扩展函数。
