International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / An advanced electro-optic hybrid rotary joint (EOHRJ) has been developed in Phase II of an AF SBIR effort with Physical
Optics Corporation (POC) to replace cable wrap structure for multi-channel rotation-to-fixed (RTF) signal transmission. The
EOHRJ meets AFFTC and other range special needs with a generic, high performance, rotary joint solution. At the moment,
we have successfully installed and tested the EOHRJ on our KTM tracker system with the following capabilities: 1) able to
accommodate hundreds of transmission channels, including electrical power, control, feedback, and low-speed signals; 2)
able to accommodate multiple channel, high data rate (over gigabits per second), and bi-directional signal transmission; 3)
able to be reliable for harsh environmental operation, adaptive to stringent sized requirement, and accommodating existing
electrical and mechanical interfaces.
The completed EOHRJ contains three uniquely integrated functional rings. The first and the outmost one is power ring,
which provides RTF transmission channels for over 50 high voltage and high current channels. The second and the middle
one is low speed electrical signal ring, which provides RTF transmission for over hundred control, feedback, and low speed
data signals. The third and the inmost one is optical fiber slip ring, which, incorporating with current advanced signal
multiplexing technologies (either time division or wavelength division multiplexing ) is able to provide multiple channel,
high data rate, and bi-directional signal transmission. At the moment, the prototype module of the tree-layer EOHRJ has
been successfully assembled in Air Force’s tracker system, and is providing a satisfactory performance. This paper presents
our joint work on this project.
