Figure Lengend Snippet: ( a ) Labsphere Helios 0.5 m diameter integrating sphere in our Rochester Institute of Technology (RIT) calibration laboratory. Plasma lamps, attached to the sphere, are visible on the top shelves to the left and right. ( b ) Our Headwall imaging system in the pan-tilt unit in front of the sphere during calibration. ( c ) typical NESR curves for 10 light levels up to the maximum output of the two plasma lamps, near daylight levels. ( d ) Typical SNR obtained over the same 30 light levels for a 2.5 × 10 − 3 s integration time. Hyperspectral video sequences shown in this paper used either a 2.5 × 10 − 3 s or 3.0 × 10 − 3 s integration time.

Article Snippet: To characterize the system, we used our calibration facility, which includes a LabSphere Helios (Labsphere, North Sutton, NH, USA) 0.5 m diameter integrating sphere [ ] paired with a calibrated spectrometer to collect radiance data in order to derive system calibration curves, signal-to-noise ratio (SNR), and noise-equivalent spectral radiance (NESR).

Figure Lengend Snippet: Data collection with the integrated imaging system: Headwall Hyperspec imaging system, General Dynamics maritime pan-tilt, and Vectornav-300 GPS IMU atop a BlueSky AL-3 telescopic mast. ( a ) on the western shore of Hog Island, VA while imaging littoral zone dynamics; ( b ) on the eastern shore imaging coastal wetlands; ( c ) close-ups of the imaging system while in operation at Hog Island and in the lab during testing. Closer to the shoreline in ( a ), white Spectralon calibration panels are deployed; also visible are various fiducials (orange stakes) used for image registration and geo-referencing. Fiducials were surveyed with real-time kinematic GPS.
