Paper Abstract

The article is devoted to development of a spectroradiometer for an automatic controlled lighting system for plants cultivated in a greenhouse. The error of the spectroradiometer due to the discreteness of the multielement photodetector and the ratio of the entrance slit monochromatic image half-width to the step of the elements are considered. Relative error of photosynthetically active radiation bands ratio measurement for various instrument line functions is calculated. The results of an experiment for mass-produced optical multi-element photodetectors with different widths of sensitive elements for different entrance slit monochromatic image half widths of a polychromator are presented.
