Abstract
A high resolution hyperspectral imaging apparatus (10) for analyzing atmospheric constituents. The apparatus (10) includes an optical telescope that receives an optical beam to be analyzed. A beam splitter (20) separates the optical beam into a first beam and a second beam that have separate wavelengths. A first spectrograph (72) analyzes the first beam and a second spectrograph (74) analyzes the second beam. Both spectrographs (72, 74) include a lens assembly (36, 44), a grating (42, 50) and a detector (54, 52). The gratings (42, 50) separate the beams into representative wavelengths that are recorded by the detectors (54, 52).
