Publication number: 20220021983Abstract: An embodiment of a system includes a light source, an optical assembly, and an electronic circuit. The light source (e.g., a laser) is configured to generate a source optical signal. The optical assembly is configured to direct the source optical signal into an end of an optical-fiber assembly that includes an optical fiber having a section wrapped multiple turns around a mandrel and including mandrel zones, and to receive, from the end of the optical-fiber assembly, a return optical signal. The electronic circuit is configured to select at least one mandrel zone in response to a component of the return optical signal from the at least one mandrel zone, and to detect an acoustic signal incident on the mandrel in response to the component of the return optical signal.Type: ApplicationFiled: September 3, 2021Publication date: January 20, 2022Applicant: Adelos, Inc.Inventors: Stephen Timothy Doll, Peter S. Lovely, James Alexander Philp, John R. Providenza, Timothy N. Roberts, Leon J. Stevens, Philip J. Stimac

Patent number: 9766141Abstract: Systems and methods are disclosed for dynamic addressing of optical fiber sensors in fiber optic interferometry systems. Events that occur along the optical fiber span have defining attributes such as location along the optical fiber span, type, magnitude, time of occurrence, and duration. The event attributes may be used to dynamically form a unique address that fully defines and identifies the event. Other information, such as the corresponding identifier for one or more of the optical fiber span and the corresponding fiber optic interrogator may be included as part of the unique address.Type: GrantFiled: May 13, 2016Date of Patent: September 19, 2017Assignee: Adelos, Inc.Inventors: Dan Alan Preston, Calvin Hewitt, James Alexander Philp
