Publication number: 20100232031Abstract: A fluidic lens may have a transparent window member, a transparent distensible membrane, an inner ring between the window member and membrane, and a top ring disposed such that the membrane is between the piston ring and the inner ring. A layer of liquid may be stored between the window member, the inner ring and the membrane. The top ring may be adapted to apply a liquid displacement force to the membrane in a direction perpendicular to a plane of an aperture of the inner ring to cause a change in a radius of curvature of the membrane. The membrane may be pre-tensioned prior to assembly with the other components.Type: ApplicationFiled: April 12, 2010Publication date: September 16, 2010Applicant: HOLOCHIP CORPORATIONInventors: Robert G. Batchko, Andrei Szilagyi

Publication number: 20100208357Abstract: A fluidic lens device capable of providing variable focal power with reduced optical aberration is disclosed. The device includes a lens member and an actuator. The lens member comprises one or more elastic optical surfaces, a compliant support member in communication with the optical surfaces, and a fluid-filled chamber. The optical surfaces have a high value of elastic modulus, reducing coma and other aberrations associated gravity and acceleration. The support member may provide a compliant fluid seal and allow the edges of the optical surfaces to pivot, reducing spherical and other aberrations. One or more piezoelectric ring-bender actuators may provide the force required for compressing the support ring and deflecting the optical surfaces. The actuators may be configured to provide the fluidic lens device with reduced sensitivity to changes in temperature.Type: ApplicationFiled: February 16, 2010Publication date: August 19, 2010Applicant: Holochip CorporationInventors: Robert G. Batchko, Andrei Szilagyi

Publication number: 20100128358Abstract: A fluidic viewfinder device may include a support member having an opening forming an aperture and a fluidic lens disposed at least partially in communication with the aperture and support member. The fluidic lens may comprise a first optical surface and a second optical surface, one or more of which includes an elastic membrane. A fluid may be enclosed in at least a portion of the fluidic lens. The optical properties of the fluidic lens may be changed by displacement of the fluid, e.g., due to movement of a slide member or a rotating yoke.Type: ApplicationFiled: November 17, 2009Publication date: May 27, 2010Applicant: Holochip CorporationInventors: Andrei Szilagyi, Robert G. Batchko

Publication number: 20100128357Abstract: A fluidic stabilized focus device comprises a fluidic lens core and a first yoke. The fluidic lens core includes a support ring, a first surface that includes an elastic membrane, a second surface, and a volume of fluid enclosed within the boundaries of the first and second surfaces and support ring. The first yoke has an annular portion configured to engage the first surface. Engagement of the first surface by the first yoke results in a displacement of the fluid and a change in optical properties of the device.Type: ApplicationFiled: November 17, 2009Publication date: May 27, 2010Applicant: Holochip CorporationInventors: Andrei Szilagyi, Robert G. Batchko

Patent number: 7672059Abstract: An electrostatically actuated fluidic device capable of providing a variable focal length lens is disclosed. The device includes an elastic capacitor section, an elastic lens section in fluid communication with the capacitor section, the elastic lens section being characterized by a focal length and a fluid capable of fluid motion disposed at least partially in the capacitor and lens sections. A voltage may be applied to the capacitor section causing it to deform, which causes a portion of the fluid to flow into or out of the lens section. As a result, a change in volume of fluid in the lens section causes it to deform resulting in a variation in the focal length of the lens section.Type: GrantFiled: May 11, 2007Date of Patent: March 2, 2010Assignee: Holochip CorporationInventors: Robert G. Batchko, Justin Mansell, Andrei Szilagyi
