    摘要： An endoscope realized as either a borescope or a fiberscope including one or more fluid filled lenses is described. In an embodiment, the optical power of the fluid filled lenses may be adjusted to adjust the focal length associated with the endoscope. Thus, variable working distances are allowable while maintaining focus on an object in front of the endoscope. The endoscope may include a distance sensor, which is used to determine a distance between the endoscope and a sample. A processor may compare the measured distance to the current optical power of the one or more sealed fluid filled lenses. The processor may transmit signals to one or more actuators coupled to one or more sealed fluid filed lenses to change the optical power of the one or more sealed fluid filled lenses based on the comparison.

    摘要： A variable focus lens apparatus includes at least one rigid optical disc, at least one flexible optical membrane and at least one layer of a transparent fluid that is in communication with a fluid channel and a reservoir. When incorporated in a spectacle lens, the lens system enables wearers to adjust the power of each lens individually, so as to achieve the preferred binocular visual performance, consistent with maximum stereopsis and binocular fusion at any desired object plane.

    摘要： A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.

    摘要： A mechanism allows for changing the optical strength of a liquid-filled lens having a cavity filled with fluid. A reservoir contains additional fluid and is in fluid communication with the cavity, and the mechanism draws fluid from the reservoir into the cavity or pulls fluid from the cavity back into the reservoir, whereby a change in the amount of fluid within the lens cavity changes the lens's optical strength. A membrane seals the reservoir, and a plunger impinges upon the membrane. A movement device, such as a barrel screw or lever, moves the plunger in a controlled manner toward the membrane to increase pressure within the reservoir and thereby force fluid out of the reservoir into the lens cavity, and away from the membrane to decrease pressure within the reservoir and thereby withdraw fluid from the lens cavity and into the reservoir.
