Here we present implementations snapshot–image reorganization/mapping techniques including IMS (Imaging Mapping Spectrometry), and high density fiber image processors. These instruments are compact, non-scanning / high speed and provide high light throughput. The general principle of these methods is based on mapping areas (pixel, lines) of the object/scene on a large format CCD/CMOS to create void regions for spectral spread and simultaneous 3D+ data acquisition. This allows for a rapid detection and/or for increased SNR. High light throughput allows imaging at ultra-short acquisitions (entire cubes) down to microsecond levels. Our newest implementations include gas detection, environmental imaging and compact UAV applications. This presentation describes advantages of IMS, and fiber based systems and compares them to other snapshot techniques (computational methods). Examples of remote sensing results are presented (vegetation/crops assessment).
