Abstract: A method for the determination and deconvolution of the signature of an unknown, non-impulsive source signal. The method supposes that an array of receivers is positioned at the earth's surface to detect and record the seismic signals resulting from the interaction of the source with the earth's subsurface. The traces of data recorded are time-shifted by an amount determined by a coherency analysis of the data. The signal is estimated from the time-shifted data with a weighting factor applied at each trace. A deconvolution filter is determined from the estimate and is weighted at each frequency according to the strength of the source at that frequency. The filter is then applied to the time-shifted data.

Abstract: Optical fibers (15, 16) are spliced by securing them in end-to-end relationship in a tube (10, 61, 71). Tinted epoxy is inserted into the bore (12, 64, 74). One fiber is inserted into the bore until its endface reaches the center thereof. As the second fiber is inserted into the other end of the bore, the length of the epoxy column in the bore is observed to diminish as epoxy is displaced into venting means (14, 78) associated with the bore. When the second fiber begins to buckle, movement thereof is stopped. The central region of the tube is inspected to ascertain the disappearance of the epoxy column (54). This indicates that the endfaces are in abutment. The tube may contain an integral lens (65, 75) for viewing the fibers in the bore. A stripe of appropriate color (63) on one side of the bore provides the contrast to enhance the visibility of the tinted epoxy.
