A means of mapping the polarization across a laser beam 1 comprising the steps of dividing the laser beam into six beams 11, 12, 21, 22, 31, 32 each having a different polarization and phase. Measuring the intensity of each beam in charge coupled devices 111, 112, 121, 122, 131, 132, having an array of pixels. Matching the pixels in each array to their proper portion in laser beam 1. Adding the values obtained in each pixel to obtain a composite polarization map.
