Patent GB-2529228-A (GB)
Title: An interference system and an interference method
Inventor: YUAN ZHILIANG
IPC: H04B10/70
Filed: 2014-08-14
Abstract: A master laser outputs a sequence of phase-randomised optical pulses, which serve as pulse injection seeding for a slave laser and cause the slave laser to also output a sequence of phase-randomised optical pulses. The lasers are preferably gain-switched lasers. The jitter of the pulses output by the slave laser is less than the jitter of the pulses output by the master laser. This reduction in jitter is achieved by synchronising the periodic electrical driving signals of the master and slave lasers such that light from the master laser is in the cavity of the slave laser before the slave laser gain modulation is raised above the lasing threshold. One slave light pulse is generated during each period of time when a master light pulse is received. The output from the slave laser is input to an interference system, such as an interferometer or beam combiner, which may form part of a random number generator (RNG) (Fig. 9) or a quantum key distribution (QKD) system (e.g. Figs. 10 and 13).

Title: Methods and systems for quantifying coherency and constraining coherency-based separation in simultaneous shooting acquisition
Inventor: BAARDMAN ROLF HUIBERT
IPC: G01V1/36
Filed: 2015-02-26
Abstract: This disclosure presents methods and systems for deblending blended seismic data obtained during simultaneous shooting acquisition (SSA) into deblended seismic data gathers. Blended data is recorded by receivers wherein the data is generated by simultaneous activation of multiple sources at different positions with dithered time delays. A residual is calculated based on the blended data and time delays. A plurality of pseudo-deblended residuals are calculated wherein each pseudo-deblended residual is the residual aligned in time with an activation time of one of the sources. Deblended gathers are iteratively calculated from the pseudo-deblended residuals. Each deblended gather represents seismic energy produced by one of the sources. Preferably calculating the residual comprises calculating a difference between the blended seismic data and deblended gathers shifted by corresponding time-delay. The blended seismic data is iteratively separated into the deblended seismic data gathers based on semblance analysis of a residual difference between the blended seismic data and the deblended seismic data gathers.
