Optimum Techniques for Measuring Spectral, Spatial and Temporal Distribution of Radiation

Abstract

It is planned to send an infrared scanner in a balloon up to high altitudes. Azimuth scanning is accomplished by the torsion of the gondola. The elevation angle of the scanning telescope is incremented stepwise after each full revolution. In this report the scanning mode is studied and improvements thereof are suggested. For a follow-up instrument it is suggested that the scanning rate should not be limited by the slow torsion. In a next approach the elevation would be scanned fast compared to the torsion. Ultimately a 'Multiplex Scanner' should look at many directions simultaneously. The principle of a multiplex scanner is outlined.
