Abstract. A new projection technique for mathematical construction of pole figures (PF's) on the basis of a model Gauss-shaped orientation distribution function (ODF) of microcrystallites is suggested. The problem of Ghost phenomena which is characteristic for the series expansion methods in quantitative texture analysis is shortly discussed. The formulae describing the relationship between the model ODF and the constructed PF's are derived and covered by a procedure for application of projection technique which avoids the appearance of ghost peaks. Some results are shown.
