    Abstract: An optical apparatus has a light detecting section which detects light and emits transmitted light where linearly polarized light, which is converted by a polarizing section, is transmitted through a subject. In addition, the optical apparatus has an orthogonal separating section which orthogonally separates the emitted light from the light detecting section and a light reception section which receives light which is orthogonally separated by the orthogonal separating section. A calculation apparatus outputs a rotation control signal to a rotation apparatus and rotation controls the light detecting section so that the rotation plane is orthogonal with regard to an optical path of the transmitted light. Then, the calculation apparatus measures the polarization state of the transmitted light, which is transmitted through the subject S using the intensity with which the light, is received by the light receiving section.

    Abstract: Aspects of the subject technology relate to methods and systems for removing haze from an input image. The system includes a polarimeter configured to receive an input image, the input image comprising haze corresponding to light scatter. The polarimeter is further configured to produce plural Stokes values based on received input image. The system also includes a signal processor coupled to the polarimeter. The signal processor is configured to determine a peak angle and a valley angle for the input image based on the plural Stokes values, where the peak angle corresponds to an angle at which the input image has the most amount of light scatter passing therethrough, and the valley angle corresponds to an angle at which the input image has the least amount of light scatter passing therethrough. The signal processor is further configured to perform removal of the haze from the input image based on the determined peak and valley angles.
