ISSUES ON OPTIMIZATION OF THE LASER SCANNER FUNCTIONING IN THE DEFORMATION MEASUREMENTS REGIME

Abstract

The article is devoted to the issues of optimization of the laser scanner functioning in the regime
of deformation measurements. The task is formulated on taking into account the effect of back
scattering of laser beam during assessment of the quantity of recognizable gradations in the reflected
laser beam, and therefore, during evaluation of information characteristics of the laser scanner when
performing deformation measurements. The solution to the formulated optimization task on controlling
the laser beam power, with consideration to the limitation condition imposed on the sought-for
function, does show that in case of linear functional dependence between the beam power and the
distance to the studied object, the informativity of the carried out cycled measurements can reach
the minimum value. This fact indicates to the necessity of practical realization of the function of
adaptive control with inverse dependence of the laser beam power on the distance between the laser
and the studied object.
