The present invention includes systems and methods for quantitative and qualitative imaging of gases, vapors, fumes, and the like. In one embodiment, the system uses a moving, or a rotating filter for alternately capturing on-line and off-line images of a scene that potentially includes the target gas of interest. The moving, or rotating filter includes at least two filter segments for transmitting (a) wavelengths corresponding to a spectroscopic absorption feature for on-line elements of the target gas, and (b) nearby wavelengths not corresponding to a spectroscopic absorption feature for off-line elements of the target gas. An image processor executes an algorithm for transforming the collected on-line and off-line data, corresponding to different pixels in the imaging array, into an image map of path-integrated concentration, or concentration path lengths (CPLs). The systems and methods of the invention do not use active light sources to illuminate the target gas. Instead, imaging and processing is done entirely using passive received energy from the target gas.

System and method for passive remote detection of gas plumes

Methods, systems, and computer program products for analyzing an imaging system or an image produced by the imaging system are disclosed. The imaging system is configured to sense a target on a background and the target, background, and imaging system are associated with spatial information and spectral information. The imaging system or image is analyzed by, first, determining two of a spatial confidence level associated with the spatial information, a spectral confidence level associated with the spectral information, and a total confidence level associated with sensing the target on the background. A non-determined one of the spatial confidence level, the spectral confidence level, and the total confidence level is then calculated responsive to the determined confidence levels for use in analyzing the imaging system or image.

Imaging system analysis methods and apparatus

Apparatus and methods for detecting and analyzing spectral polarimetric images are disclosed. Spectral polarimetric images are detected by selecting spectral bands of light within light received from a light source and capturing polarimetric images of the selected spectral bands of light. Spectral polarimetric images are analyzed by converting spectral polarimetric images to Stokes images and selecting two or more of the Stokes images for analysis.
