摘要： Method and system for identification of a changed state of a fluid with respect to a reference state of the same fluid, the fluid having an optical parameter changing with the change of the state of the fluid. The method comprises: a) providing an optical arrangement including a transparent enclosure with a portion of the fluid, and an object observable through the optical arrangement, the arrangement being designed such that an image of the object in the changed state of the fluid is optically distinctive from an image of the object in the reference state of the fluid due to change of the optical parameter, at least one of the images being predetermined; b) illuminating the object with diffuse light; c) observing a current image of the object though the optical arrangement along an optical axis; and d) comparing the current image to the predetermined image to identify the changed state of the fluid. The comparison and the identification may be performed by eye or by a sensor with a logical circuit.

摘要： An optical indicator (130) for identification of a changed state of a fluid with respect to a reference state of the same fluid, or for monitoring or checking or authenticating a fluid. The fluid has an optical parameter that changes with the change of the state of the fluid. The optical indicator (130) may be attached to or integral with a container or packaging (132) for the fluid. The indicator (130) includes a cavity configured to be filed with the fluid such that the fluid filled cavity forms a variable optical element having an optical performance that varies depending on the changeable fluid's optical parameter. The fluid filled cavity coupled to other optical components of the indicator provides an image that may be compared to a reference image to detect a change of at least one optical property of the fluid as compared to the reference fluid. The comparison may be performed visually or by a suitable detector. The comparison may include automated processing of the detector's output signal(s).
摘要翻译：一种光学指示器（130），用于识别流体相对于相同流体的参考状态的改变状态，或用于监测或检查或认证流体。流体具有随流体状态变化而变化的光学参数。光学指示器（130）可以附接到用于流体的容器或包装（132）上或与其一体。指示器（130）包括构造成与流体一起提供的空腔，使得流体填充腔形成具有根据可变流体的光学参数而变化的光学性能的可变光学元件。耦合到指示器的其他光学部件的流体填充腔提供可以与参考图像进行比较的图像，以检测与参考流体相比流体的至少一个光学特性的变化。比较可以在视觉上或通过合适的检测器进行。比较可以包括检测器的输出信号的自动处理。
