Digital array scanned interferometer: sensors and results

Digital array scanned interferometers (DASI) blend characteristics of a grating spectrometer and a two-beam interferometer for acquisition of hyperspectra. DASI's posses field-widened capabilities that permit very high throughput. Aspects of DASI design, hyperspectra, and data processing methods are presented. In particular, we provide data showing that photon-noise-limited hyperspectra are achievable for DASI data.
