Taschenbuch. Zustand: Neu. Neuware - A field deployable hyperspectral imager utilizing chromotomography (CT), with a direct vision prism (DVP) as the dispersive element, has been constructed at AFIT. This research is focused on the construction and characterization of a CT imager as prototype for a follow on International Space Station based instrument. The instrument is currently the fastest known direct vision prism hyperspectral CT imager. The imager was capable of acquiring spectral data for a transient event lasting less than 0.12 s. The ability to identify potassium, sodium, and absorption features from the instrument's acquired data shows the potential this imager possess. This research has shown that the instrument has the ability to capture data of static scenes, and more importantly, the imager acquired spectral data for rapidly evolving scenes. Because CT imaging has the potential ability to capture spatial and spectral data from transient events, a space-based system may enhance current capabilities of identifying, classifying, and characterizing battlespace events such as artillery/AAA muzzle flashes, detonations, and missile launches.…

8pp., landscape 16mo. An attractive little pamphlet, in the form of a letter 'To any whose privilege it is to have seen the Passion Play'. The pamphlet ends with five points, the last of which is: 'In rthe event of a repetition of the Passion Play in 1900, to urge Christians who may attend it to go in the spirit of pilgrimage, and to make provision for the spiritual interests of those who are present at the Play.' Very good, on lightly-aged paper. Scarce: the only copy on COPAC at Oxford, and no copy on OCLC WorldCat. From the papers of Sir Francis Henry Evans, whose wife Marie was of American extraction.…
