Patent number: 10473818Abstract: A system for detecting gas leaks and determining their location and size. A data gathering portion of the system utilizes a hub and spoke configuration to collect path-integrated spectroscopic data over multiple open paths around an area. A processing portion of the system applies a high-resolution transport model together with meteorological data of the area to generate an influence function of possible leak locations on gas detector measurement paths, and applies an inversion model to the influence function and the spectroscopic data to generate gas source size and location.Type: GrantFiled: January 31, 2019Date of Patent: November 12, 2019Assignees: The Regents of the University of Colorado, a body corporate, Government of the United States of America as represented by the Secretary of CommerceInventors: Gregory B. Rieker, Ian Coddington, Nathan R. Newbury, Kuldeep Prasad, Anna Karion

Patent number: 8558993Abstract: A coherent laser radar that uses two coherent femtosecond fiber lasers to perform absolute ranging at long distance. One coherent femtosecond fiber lasers acts as a source and the other as a local oscillator for heterodyne detection of the return signal from a cooperative target. The system simultaneously returns a time-of-flight range measurement for coarse ranging and an interferometric range measurement for fine ranging which is insensitive to spurious reflections that can cause systematic errors. The range is measured with at least 3 ?m precision in 200 ?s and 5 nm precision in 60 ms over a 1.5 m ambiguity range. This ambiguity range can be extended to 30 km through reversal of signal and LO source roles.Type: GrantFiled: September 16, 2010Date of Patent: October 15, 2013Assignees: The National Institute of Standards and Technology, as Presented by the Secretary of Commerce, The United States of America as Represented by the Secretary of CommerceInventors: Nathan R.
