An interferometric long-wavelength infrared (LWIR) hyperspectral imager is demonstrated, based on a Michelson corner-cube interferometer. This class of system is inherently mechanically robust, and should have advantages over Sagnac-interferometer systems in terms of relaxed beamsplitter-coating specifications, and wider unvignetted field of view. Preliminary performance data from the laboratory prototype system are provided regarding imaging, spectral resolution, and fidelity of acquired spectra.

A flexible tool for collection of data from imaging sensors is presented. It is compatible to Windows XP and later. It is designed to meet demanding requirements in scientific applications and has been evaluated both in laboratory measurements and extended field trials. Main features of the image capturing software, denoted D8, are:• D8 supports various kinds of cameras: monospectral, multispectral and hyperspectral. A new camera is included by adding additional information in a configuration list.• The image data acquired from D8 are standardized into formats based on the ENVI format.• Each single image gets a timestamp with the precision of 1 ms. There is support for an FPGA board, which can improve the precision to 1 μs. • Through D8 an arbitrary number of cameras can be temporally synchronized and the data collected. This options imitates true multi-colour cameras.Results from a temporal synchronization and spatial alignment of two multiband cameras are presented.
