Abstract
It is critical to extract maximum information from IR images for target detection, identification and classification systems. The physical information in an image is contained in basically four parameters namely the intensity, phase, polarization andwavelength of the received light. Besides acquiring intensity variations, rapid collection of corresponding polarization signatures at desired wavelengths would enhance the information content of an IR-scene. In this regard, Coherent Technologies, Inc.(CTI) proposed an active device that simultaneously measures the spectral intensity and polarization content of an image in real time over the MWIR and LWIR spectral regions. The device will generate four images that correspond to each of the Stokesvector components. From Stokes components, degree and type of polarization of a scene can be ascertained. In Phase I, design specifications of all critical components of an all-solid-state, compact, spectra-polarimeter that included a broadly tunableoptical parametric oscillator, an acousto-optic tunable filter, a
