The contamination sanitation inspection system (CSIS) allows a user to capture an image of a large scene (such as a food processing line, a food service facility, a food products storage area, or a plant production area/facility) and identify contamination within the scene and preferably represent the contamination on a spatially accurate map (or floorplan) so that contamination within the inspection map area is clearly identified and recorded for subsequent treatment. In an alternative embodiment, the CSIS also includes a decontamination system to sanitize any identified contamination.

Active illumination-based multispectral contamination sanitation inspection system

A line scan imaging system scans a targeted inspection area and gathers reflectance and fluorescence data. The inspection system comprises at least a rotatable/pivotable mirror-faced triangular prism, a line illumination source, and a line scan hyperspectral camera. The prism has a mirrored camera face and a mirrored illumination face. In operation, as the prism rotates, the camera instantaneous field of view (IFOV) and the projected illumination line converge at a nadir convergence scan line so that the hyperspectral camera receives line scan data from the nadir convergence scan line as the nadir convergence scan line traverses an inspection area.

Method and system for active line scan imaging

A line-scan laser is directed to a sample so that a Raman-shifted light signal is emitted from the sample. An imaging spectrograph and associated camera and processor acquires the Raman-shifted light signal and processes the signal to thereby identify the composition of the sample.
