Paper Abstract

The paper presents reflectance characteristics of plants. The objects of the research were the selected plants, taking the various levels of organization and structure into consideration, as well as the state of plant health and growth. Reflectance spectrum was analyzed in the range of wavelengths from 0,2 to 2,5 μm. The values of reflectance for three wavelengths (λ1=850 nm, λ2=905 nm, λ3=1550 nm) were analyzed with the particular emphasis. The sample tests were performed immediately after biological material taking and in the several 24-hour time intervals. The time intervals enabled the process of plants wilting and drying. The reflectance measurements were repeated until the moment of plant complete dried out. All measurements were performed with the use of the spectrometer Lambda 900 (Perkin Elmer) equipped with the 150 mm integrating sphere PELA1001 dedicated for the measurements of the hemispherical reflectance both of diffuse and specular type. On the basis of the obtained results one calculated the values of signal ratios for the three selected wavelengths: 850/1550nm, 905/1550nm, and 850/905nm. The collected spectra and reflectance characteristics enabled the analyses of both results similarities and differences, which enabled the determination of the reflectance changes tendency associated with the typical processes occurring in plants. The analyses of plants reflectance characteristics were made for the use of the laser system for identification of terrain elements and their physico-chemical properties.
