Abstract:
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.

Claim (Index 9):
A method comprising:\n modulating an output wavelength of a laser; transmitting a portion of the laser output to a surface; spatially scanning the transmitted portion of the laser output; receiving a portion of the laser output scattered from the surface; producing a laser wavelength modulation spectroscopy signal from the received scattered laser output; and filtering the laser wavelength modulation spectroscopy signal to reduce measurement noise caused by spatially scanning the beam.
