The reflectance profilometer, constructed in Institute of Optoelectronics, Military University of Technology, is an optoelectronic device based on the laser remote sensing technique, designed for use on unmanned aerial vehicles. The main task of the profilometer is to analyze the reflectance signals for laser radiation from the multispectral range: 850, 905, and 1550 nm. On the basis of the analysis the profilometer enables two fundamental functions: to define the shape of the ground and identify elements of terrain coverage, along with analysis of its physicochemical properties. The reflectance profilometer is a system based on a modern concept of measurement, allowing to obtain unique information about tested objects, whose measurements or detection are not possible by means of thermal imaging systems and systems operating in the visible range. The received information is visualized in 3D format, which allows for more accurate, precise and comprehensive way of analyzed area model presentation.

Examined praseodymium doped crystals with 1 at.% of Pr^{3+} ions for Y_{3}Al_{5}O_{12} (YAG), SrLaGa_{3}O_{7} (SLGO) hosts and 3 at.% of Pr^{3+} ions for YAlO_{3} (YAP) hosts were produced using Czochralski method. The luminescence for the range of 200÷800 nm and absorption spectra for a wide range of 200÷6000 nm, for Pr^{3+}:YAG, Pr^{3+}:SLGO and Pr^{3+}:YAP crystals have been measured. A free-running laser emission of λ=0.744 μm for Pr:YAG and λ=0.729 μm for Pr:SLGO for two different transmissions of output mirrors has been obtained.

Optical features (absorption and luminescence spectra) for Er^{3+} doped yttrium-aluminium garnet (YAG), yttrium orthoaluminate (YAP) and LiNbO3 crystals as well as their changes after UV and gamma irradiations are presented. Possibility of gamma-induced sensibilization process in Er^{3+} doped crystals is discussed. Positive result for non-pre-annealed gamma-irradiated rods of Er^{3+}:YAG crystal was stated.

The spectroscopic properties of trivalent dysprosium (Dy^{3+}) doped LiNbO_{3} crystals have been investigated at various temperatures. Absorption, emission, excitation and lifetime measurements have been performed and discussed in the framework of Judd-Ofelt approach. The stimulated emission cross sections of the strongest transitions of Dy ^{3+} ion have been estimated. A stimulated emission has been demonstrated in the near infrared.
