The paper presents the results of on-board and field tests of an upgraded model of a visible-near-infrared imaging spectrometer with high spectral and spatial resolution and diffraction grating polychromator. A series of monochrome images and spectral reflectances for different background-target situations were obtained by aerial surveys and ground measurements from a rotating platform. The images clearly traced changes in luminance contrast of natural and artificial objects near the red edge of the visible range. The spectral reflectance of lawn areas, contaminated with sodium chloride and copper sulfate showed that spectral aerial survey can detect and map the affected vegetation areas at early stages of contamination prior to appearance of morphological changes in plants. High quality of the results of the flight and field studies and the reliability of the device allow us to recommend it as a basis for creation of device prototypes for operation onboard small spacecrafts and ground work.
Keywords: imaging spectrometer, hyperspectral photography, monochrome images, spectral reflectance
