Abstract :
In this paper a magnetooptical method for measuring the positions of light beams is described. It is based on the spatial light modulation produced by domain wall motion in the orthoferrite crystal. The presented method provides a measurement accuracy of 0.8 μm and a sampling time of about 1 μs
