The invention discloses an active type optical imaging device of a common optical path panorama belt with polarization target enhancement. The active type optical imaging device of the common optical path panorama belt with the polarization target enhancement comprises a panorama belt polarization illumination system and a panorama belt polarization imaging system, a large vision field panorama belt optical system is used as the basic form of illumination and imaging, the illumination system and the imaging system have a common optical path, an illumination light source and an imaging camera are arranged at two sides of a spectral component respectively, and a polarization device combination is used as the spectral component of illumination lights and imaging lights. According to the active type optical imaging device of common optical path panorama belt with the polarization target enhancement, a key target detection with high contrast at a large vision field range is achieved, differences of polarization-maintaining performance between a target object and a background object are utilized, can enhance the contrast between the key target object and background environment can be enhanced, and it is advantageous for target detection and tracking. An active imaging method is taken to provide more real and effective polarization-maintaining performance information of the object, and the signal-to-noise ratio is higher. A common optical path design is adopted, the robustness of the system to the vibration and other environmental factors is enhanced, and the device is compact in structure and light in volume and can be applied to worse working environment.
