Abstract:

The patent concerns an optical transmit and receive terminal which controllably couples light energy out of a continuous fiber optic bundle by positioning a controllable acoustic energy source to change the refractive index and thus diffract a portion of the transmitted light energy out of the continuous fiber optics without interrupting or severing any of the light transmitting fibers. A portion of transmitted light modulated with signal information may thus be diffracted out of a continuous fiber optic bundle for detection of the information contained therein without in any way interrupting the continuity of the optical fibers.
