OPTIMIZATION OF DERIVATIVE SPECTRAL CHARACTERISTICS OF MULTI-COLORED OBJECTS UPON REMOTE DIAGNOSTICS
(pp. 60-63)

Abstract. The authenticity of remote diagnostics of multicolored objects requires providing the true representation of all colors hues which can be quaranteed by help of modern multichannerl hyperspectrometers. The paper is devoted to research of condditions of optimization of utilization of method of second derivative upon diagnostics of multispectral objects. It is wellknown that the second derivative of spectral characteristics of multicolored objec is relatively non-sensitive for variations of illumination of researched object but sufficiently sensitive for noise signals and in such conditions 6the task of minimization of noise effect or filtration of them gains a special importance. The stressed out properties of the second derivative method, namely the capability to amplify the specific low spectral elements and their strong subjection to impact of noises make it possible to develop the information criterion to determine the optimum type of main and derivative spectral characteristics of tested object. An example for utilization of suggested croterion by way of interrelasted calculation of hyperspectral information charsacteristics asnd its second derivative using the Eyler–Lagrange equition solution of which provide for extremum of information content of severely noised hyperspectral diagnostic signals.

Keywords: remote diagnostics, multicolored object, optimization, authenticity, spectral characteristic, hyperspectrometer.
