COMPUTER CONTROL OF PLASMA SEPCTROSCOPE

摘要

A method and apparatus to optimize a characteristic of measured data in an adjustable instrument for chemical analysis. The characteristic is measured at a plurality of adjustment points about a start point. Through parabolic interpolation of the data a conjugate vector is formed and the best operating point thereon is selected. Then measurements of the characteristic are taken as a function of the adjustable parameters about the best point on the conjugate vector. These data are used in a parabolic interpolation to define a second conjugate vector. The best operating point on the second conjugate vector is the optimum point of the instrument.
