Presentation Transcript

  1. Push broom imaging • Use only a linear array of detectors • Spacecraft motion sweeps this array along the surface • Field of view sets Swath width • Number of pixels sets pixel-scale

  2. Stereo Imaging

  3. Hyper-spectral imaging • Each pixel in the image has a spectra • Like taking hundreds of images at different wavelengths

  4. How it works • Pushbroom imaging again • But with a 2D CCD array Bands Blue to Red Across-track pixels Across-track pixels
