Abstract
A scanning system of a high accuracy double-wedge is presented, which allows us to perform very small angle deviation of a passing beam in a simple way. The first wedge's principal section is perpendicular to the horizontal axis, and the second is to the vertical axis correspondingly. They respectively rotate around the horizontal axis and the vertical axis as they work. So different small rotation angles of two wedges determine the corresponding orientation and position of the passing beam, and then high accuracy and very small-angle beam deviation can be performed. According to the design result: when the wedge angle is 5°, the refraction light beam will change about 1<i>μrad</i> if the wedge is rotated 1<i>arc</i>min; the scanning range of light beam in the horizontal direction and the vertical direction can be not less than 600<i>μrad</i>, and the scanning precision of the device can be superior to 0.2 micro <i>μrad</i>
