Abstract: Disclosed are first and second embodiments of a 3-channel probe-plate structure of the fiber-optic interferometer, wherein low-coherent-length light from a superluminescent light-emitting diode is split by a tree splitter into three light branches which are coupled as separate light inputs to the probe-pate structure by single-mode, polarization-preserving optical fibers. For each of the 3 channels, the first embodiment of the probe-plate structure comprises an integrated polarizing lithium-niobate Y splitter-modulator for deriving separate reference-arm light and probe-arm light.

Abstract: A brassiere pad is formed by providing two cones, each consisting of batting and having a seam extending from the cone apex to its periphery; nesting the cones to orient the seams in selected non-superposed position; and applying heat and pressure to the cones to effect their compression to final pad shape and interconnection through curing of a bonding agent.
