Research of Laser Screens of Electronic Optical Targets

Abstract

The paper presents the results of researches on development of laser screens of electronic optical targets for small arms at Computer facilities department of Kalashnikov ISTU and at Institute of Mechanics, Ural Branch of the RAS. The electronic optical targets featured by high precision and noiseproof properties, but at the same time bulkiness of a design, high energy consumption and labor input of control are widely used for test and diagnostics of small and artillery arms on productions and military acceptance and improvement of their operational properties are the relevant task. Options of a design of laser screens with use of mirror lattices and laser planes are investigated. At first the choice of photo diodes for optical sensors and the modes of their work proceeding from a ratio signal/noise and duration of the front of a signal is carried out. Further parameters of a laser mirror lattice are investigated; such shortcomings as essential weakening of a laser beam at repeated reflection, labor input of mechanical control of a lattice and existence of "dead zones" in the near mirror areas are revealed. But restriction of the sizes of the check-in area allows to use nevertheless laser mirror lattices for special cases of tests. The laser plane on the basis of the laser level is also investigated. Proceeding from the small level of a useful signal it is necessary to use slot-hole diaphragms, the optical system and the electronic scheme of strengthening. Complication of a design of the laser plane has allowed to receive the best ratio signal/noise, but the optical system and parameters of the laser level also limit the check-in area sizes to smaller values, than at a laser mirror lattice. Results of experimental tests of laser screens are given. The conclusion is drawn on prospects of further researches and improvements of optical targets for the purpose of expansion of their spheres of use and decrease in prime cost.
