<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The article discusses a technical solution for improvement of alignment measurement tools by means of a laser beam as a reference baseline and photoelectrical recorder of high accuracy, wide range and capacity. It also provides a brief review of classifications of modern primary transducers of alignment measurements which forms the basis for a patented design and an electronic block diagram of a photoelectric alignment fixer with an opto-electronic analyzer. The proposed device, in contrast to modern analogs, has small weight and size parameters and provides high efficiency of retrieval of data re straightness deviations. The electronic block diagram and the mechanical design of the device are based on linear, transverse scanning with photoelectric fixation relative to the energy center of the laser beam and registration using the signal decay method.</span></span></p>
