Abstract
AOTF is a solid state electro-optical device which acts as an electronically tunable spectral filter. The specific point of the device is that we can simultaneously obtain two diffracted beams perpendicularly polarized to each other. So we developed an imaging spectro-polarimeter employing a visible (450-700 nm) AOTF as well as a visible and up to near infrared (500-1, 000 nm) AOTF. This paper first presents the concept, configuration, performance of the instrument and, examples of laboratory as well as field measurements. Then advantages and disadvantages of the instrument are discussed when installed in such an artificial satellite as ADEOS.
