Abstract
A system is provided for transmitting data through an optical fiber. A beam of light is directed into the optical fiber. A plurality of selective wavelength filter-mirrors are interposed adjacent the optical fiber. Each of the filter-mirrors is operable to reflect only a selected color and to transmit other colors. Each of the filter-mirrors moves relative to the optical fiber in response to a variation of a selected parameter, to vary the quantity of light being reflected by the filter-mirror. Variation of different selected parameters causes movement of corresponding selective wavelength filter-mirrors and concomitant reflection of corresponding selected colors. The quantity and color of the light being reflected are detected by a plurality of selective wavelength transmission members. Each of the transmission members is operable to transmit only a selected color. The quantity and color of the light transmitted by each transmission member are sensed. The illustrative embodiment concerns an optical pressure catheter which transmits data utilizing the described system.
