摘要:
The present invention is a limited rotation Fiber Optic Rotary Joint (FORJ) of one or more optical channels. This will enable one or more optical signals to pass across a rotational interface for a fixed number of rotations. For many applications, such as a winch or certain robotic joints, an unlimited number of rotations in either direction is unnecessary. For these types of applications a limited rotation FORJ is an attractive option because they typically have lower loss, are less complex, and have higher reliability.
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.

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.

The object of the present invention is that of a slip ring which utilizes one or more pistons to transfer the external pressure applied by the environment to an incompressible fluid in the inner cavity of the slip ring, thereby balancing the external and internal pressures resulting in a nominal, if any, pressure differential. This will enable the device to operated in environments with significantly higher ambient pressures then have been traditionally possible.

A Passive Bi-Directional Off-Axis Fiber Optic Rotary Joint (FORJ) with a center bore has been invented in which an optical signal can be transmitted across a rotating boundary without using the centerline or axis of rotation of the FORJ. Rather a fiber bundle is used to transmit the optical signal across a single mechanical rotational interface.

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.

An active 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 the rotor of motors. It is an active, hi-directional rotational optical transmission device which could be used for multi-mode, or single mode fibers without the limitation to the through bore diameters.
摘要:
A multi-channel fiber optic rotary joint mechanism has been invented in which optic signals can be transmitted simultaneously from a rotating fiber optic collimator bundle and a stationary fiber optic collimator bundle through an opto-mechanical de-rotating mechanism, which includes an optic de-rotating element, an internal gear and an flexure anti-backlash mechanism. 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.
