The compact system for chromatic fiber optic spatial filtration

A simplified model was constructed for tests of chromatic spatial filtration with the use of optic fibers. Many optical bands were obtained with different predominant color components. Their distinction did not require any use of apparatus for spectral analysis. To obtain them, the direct sunlight was used as the wideband natural light source. The repeatable effect of visualization was achieved of effectiveness of optical chromatic spatial filtration in a set of optical fibers integrated mechanically with individual chromatic lens. On the model analysis basis, an arrangement of target radiometer was designed, having to make possible the automatic measurement, registration and analysis of light radiation from point source lying in well-defined spatial place, in good accordance with required spectral profile of detection. Constructional foundations of such radiometer enable to resign from the use of traditional optical (interference) filters and/or detectors of precisely predefined spectral profiles in the case of similar applications.
