Paper Abstract

Acousto-Optic Tunable Filter (AOTF) is a solid state electro-optical device which acts as an electronically tunable spectral filer. The specific point on the device is that we can get two diffracted beams perpendicularly polarized each other. So we developed an imaging spectro- polarimeter employing a visible AOTF and two CCD cameras each of which shows horizontally or vertically polarized spectral image of the object. Typical specifications of the visible AOTF imaging spectro-polarimeter completed are Spectral Range: 450 - 700 nm, Spectral Resolution: 1.2 - 1.9 nm, Spatial Resolution: 20 line pairs/mm (MTF: 0.3), Diffraction Efficiency: over 90%.
