OF IMITATION OF THE OPTICAL LOCATION DEVICE UNIFORM MOTION

Abstract

A method of physical modeling of an optical-location device (OLD) movement, based on simulating the movement of the OLD relative to the object under investigation by scanning its field of view on a fixed surface, has been proposed and developed. The application of an object modeling surface (MS) bent according to the shape of the Archimedes spiral is substantiated. The basic equation of the imitation method is determined. A comparative characteristic of three methods of scanning radiation by a spiral MS according to the criteria of complexity and scope of various OLD types has been carried out. A mathematical model of the simulation process is developed, taking into account the angular distribution of the radiation reflected from the diffuse magnetic field. The dependence of the imitation process accuracy on the OLD angle of incidence of the radiation on the MP is considered. The angular correction of the reflected radiation amplitude was determined, which formed the calculation method basis for compensating the angular error. A comparison of the field and simulation measurements results of the distance characteristics (DC) of the basic OLD layout with the calculated DC was made.
