Paper Abstract

The term `adaptive imaging spectrometer' is taken to imply that the instrumental characteristics can be adapted via purely electronic means to provide significantly altered observational capabilities. The paper demonstrates selected characteristics of the acoustooptic tunable filter (AOTF) that include simultaneous acquisition of orthogonally polarized spectral images at high spatial resolution of transmittance (greater than 75 percent), polarization contrast between the orthogonally polarized images of over 10,000, permitting accurate measurement of the polarization parameters of incident light, operation of the AOTF as a no-moving parts shutter with a contrast of about 10000 on a submillisecond time scale and electronic control of the pass band.
