Abstract
On the basis of the conducted analysis, an optical radiation positioning device is developed, the working body of which is a 3-axis differential stepper motor that allows increasing the accuracy of positioning the direction of optical radiation propagation and expanding its functionality by introducing additional rotors designed in the form of spheres placed at an angle of 90º relative to each other in mutually perpendicular planes, passing through the centers of the spheres with a possibility of angular rotation around the three axes of the rectangular coordinate system. This device is a component of optical telecommunication networks and fiber-optic communication lines and can be used as a three-axis optical radiation positioning device. In the proposed device at the value of angular rotation steps of the rotors ranging from 4.0μm to 0.2mm the accuracy of rotor positioning in a step mode of operation is 1.4÷2.1μm.
