Paper Abstract

Imaging polarimetry can be used to accurately measure wave slopes of ocean waves in real time. An imaging polarimeter measures the polarization ellipse, and hence the degree of polarization and its orientation, by acquiring a number of images each of which analyzes a different polarization state. By knowing the geometry of the camera and its relationship to the sea surface and the measured polarization quantities, the wave slope can be extracted. We have developed and tested such an instrument with good results. For this talk, the four camera imaging polarimeter operating in the visible at 60 frames per second will be presented. The polarimeter design, calibration procedures, and the data from several data acquisition programs using the instrument will be presented.
