【 摘 要 】

The main task of modern high-tech instrumentation is to increase the accuracy of devices for determining the position of the object in space. A promising direction of improvement of devices for determining the position of an object in space is the use of devices operating on the principles of laser interferometry. A method for determining the absolute position of an object in space is described. The prospects of using measuring devices based on optoelectronic devices with the use of phase methods of measuring information processing are shown. The structure of the phase measuring device based on optoelectronic devices with spatial reference points is proposed. This makes improving the accuracy of measurement by dividing into sub-bands possible.
