摘要： The present invention connects two independent plastic optical fiber channels simultaneously, in which optic signals can be transmitted along two optic passes through a single mechanical rotational interface. The first channel of light path consists of a pair of plastic optic fibers with larger-core, co-axially fixed in 2 holders respectively. The light signal from one of the fiber can be directly coupled into another fiber. A number of smaller-core plastic optic fibers for second channel of light path are circumferentially arranged in the peripheral space of the first channel fibers. They are blind-spot free during rotation and are ideal for machine control applications such as SERCOS Interfaces. The rugged design permits underwater usage. Damaged fibers can be easily replaced without costly repairs of the device itself.

摘要： A multi-channel off-axis optic slip ring system is disclosed. The invention eliminates the huge number of fiber bundles and photodiodes in most published patents. A couple of conventional optical components such as mirrors and prisms are used to transmit optical signals with high quality and low optic losses. The optical signal pick-up is realized through a pair of prisms mounted on gear transmission systems. It is a true passive, bi-directional rotational optical transmission device which could be used for both multi-mode and single mode fibers without the limitation to the through bore diameters.

摘要： An integrated electro-optical fluid rotary joint has been invented in which optical signals, electrical power, and/or signal(s), as well as fluids can be simultaneously transmitted across a common rotary-stationary interface between two relatively rotatable members for such applications, as a tethered aerostats, and tethered ROV. It consists of a main stator, a main rotor rotatable relative to said main stator. An electrical rotary joint, or slip ring, a fiber optical rotary joint, and a fluid rotary joint are integrated together on the main stator and main rotor. As a result, when the main rotor rotates relative to the main stator, optical signals, electrical power, and/or signal(s), as well as fluids from the main rotor can be transmitted to the main stator, and vise versa.

The optic de-rotating element, is positioned in the path between said rotating fiber optic collimator bundle and said stationary fiber optic collimator bundle. The internal gear mechanism provides 2:1 speed ratio for the rotating fiber optic collimator bundle and the optic de-rotating element.

摘要： The multiple channel fiber optic rotary joint of this invention can transmit an increased number of optical signals simultaneously through the de-rotating mechanism without increasing the size of the de-rotating mechanism. It also allows for the recapturing of the signals with relative ease. This is accomplished through the use of an optical condenser and/or an optical expander that reduces or expands the overall all beam structure without significantly altering the relative structure. The expanders and condensers are inverse structures in that if an optical signal is condensed when passing from right to light through the condenser it is expanded when passing left to right through the same condenser.

摘要： The present invention is a limited rotation through-bore optical slip ring. This will enable one or more optical signals to pass across a rotational interface while leaving a center bore free. The present invention is passive, unlike many off axis or through bore optical slip rings and is low loss by nature.

摘要： A fiber optic rotary joint is invented using TEC (Thermally Expanded Core) fiber. This device has a rotatable optic TEC fiber and a stationary optic TEC fiber in an assembly to convey a light beam in the optic TEC fibers. The assembly also includes a stationary optic TEC fiber holder for fixing the tip of stationary optic TEC fiber in a central hole and a rotatable optic TEC fiber holder for fixing the body of the rotatable optic TEC fiber with the tip of the rotatable optic TEC fiber protruding out of the rotatable optic TEC fiber holder. The two optic TEC fiber holders can be rotated relative to each other so as to allow the tip of rotatable optic TEC fiber to rotate in the central hole on the stationary optic TEC fiber holder with the facets of the two optic TEC fiber adjacent very closely.
