摘要： A high temperature pressure transducer and sensing apparatus to determine the deflection of the transducer diaphragm is disclosed. The pressure transducer utilizes a fused silica diaphragm (12) which is illuminated at selected locations by a coherent laser source (52) via optical fibers (38, 46). The light reflected by the diaphragm (12) forms interference fringe patterns which are focused by gradient index rod lenses (36) on the ends of optical fibers (40, 48) for transmission to a fringe counting circuit (54). By digital techniques, the fringe count is converted into a determination of diaphragm deflection.

摘要： A probe for inspecting the inner surface of a tube is disclosed. The probe (10) utilizes a group of large diameter optical fibers (12) as a light source and an annular ring (14) of smaller diameter optical fibers as interceptors of the reflected light. A pair of plano-convex lenses (16) focuses the light beam emanating from the group of large diameter optical fibers (12) onto a reflective ball bearing (18) or a concave cone (32) causing a circumferential band (44) to be illuminated on the inner surface of the tube. Light from the band (44) is intercepted by the optical fibers within the annular ring (14) and is transmitted therethrough. The transfer of light from the band (44) to the annular ring (14) is optimized by beveling the end of the optical fibers within the annular ring (14).

摘要： A variable integrated optical logic element, formed on a substrate of electro-optic material, capable of being controlled to perform the six basic logic operations AND, OR, EXCLUSIVE OR, NAND, NOR and EXCLUSIVE NOR. The optical logic element comprises a plurality of single-mode optical waveguides which form a group of parallel and series equal-arm interferometers. The optical logic element operates on the principle of constructive and destructive interference between light beams. Voltage means are provided for varying the index of refraction of certain of the optical waveguides, to produce relative phase differences in the light energy propagating therein. By inducing phase shifts in the light energy propagating in appropriate waveguides, each of the six basic logic operations can be performed. Also disclosed is an electrically passive, phase-sensitive optical coupler, which is used for switching light energy between waveguides. The switching operation performed by the phase-sensitive coupler is a function of the presence or absence of and the relative phase differences between the light energy input to the coupler.

摘要： An optical fiber having a parabolic-index profile is etched to a taper below the cladding layer. A prism contacts the taper along its length within the etched portion of the fiber, and coherent light is transmitted through the prism into the fiber. Selective control of the light beam entry angle, entry position along the taper, and control of the etching depth allows excitation of specific modes within the fiber and maximization of coupling efficiency.
