Patent number: 11921211Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for a rotating optical reflector. Optical systems may have a limited field of view, and so in order to expand the area that the optical system collects data from, the field of view of the optical system may be scanned across a target area. The present disclosure is directed to a rotating optical reflector, which includes a transmissive layer which refracts light onto a reflective layer, which has a normal which is not parallel to the axis about which the optical reflector is rotated. The optical reflector may be both statically and dynamically balanced, which may allow an increased size of the optical reflector, which in turn may increase the aperture of an optical system (e.g., a lidar system) using the rotating optical reflector.Type: GrantFiled: January 30, 2023Date of Patent: March 5, 2024Assignee: Bridger Photonics, Inc.Inventors: Peter Aaron Roos, Michael James Thorpe, Aaron Thomas Kreitinger, Christopher Ray Wilson

Publication number: 20230243648Abstract: Measurement apparatuses and methods are disclosed for generating high-precision and -accuracy gas concentration maps that can be overlaid with 3D topographic images by rapidly scanning one or several modulated laser beams with a spatially-encoded transmitter over a scene to build-up imagery. Independent measurements of the topographic target distance and path-integrated gas concentration are combined to yield a map of the path-averaged concentration between the sensor and each point in the image. This type of image is particularly useful for finding localized regions of elevated (or anomalous) gas concentration making it ideal for large-area leak detection and quantification applications including: oil and gas pipeline monitoring, chemical processing facility monitoring, and environmental monitoring.Type: ApplicationFiled: April 11, 2023Publication date: August 3, 2023Applicant: Bridger Photonics, Inc.Inventors: Aaron Kreitinger, Michael James Thorpe

Publication number: 20220412732Abstract: Measurement approaches and data analysis methods are disclosed for combining 3D topographic data with spatially-registered gas concentration data to increase the efficiency of gas monitoring and leak detection tasks. Here, the metric for efficiency is defined as reducing the measurement time required to achieve the detection, or non-detection, of a gas leak with a desired confidence level. Methods are presented for localizing and quantifying detected gas leaks. Particular attention is paid to the combination of 3D spatial data with path-integrated gas concentration measurements acquired using remote gas sensing technologies, as this data can be used to determine the path-averaged gas concentration between the sensor and points in the measurement scene.Type: ApplicationFiled: July 6, 2022Publication date: December 29, 2022Applicant: Bridger Photonics, Inc.Inventors: Michael Thorpe, Aaron Kreitinger, Stephen Crouch
