At present, spectral instruments have become widespread in various spheres of human activity, with their help it becomes possible to obtain information on the distribution of the intensity of radiation arriving at the input of the instrument from the object under study, over wavelengths. One of the possible methods for obtaining spectral information is hyperspectral imaging. A hyperspectral image is a three-dimensional data array in which each pair of spatial coordinates is associated with a set of values distributed over the spectrum. Thus, a hyperspectral camera provides complete information about the spatial and spectral structure of the object of observation. Also, the field of application of hyperspectral imaging is remote sensing of the Earth. Remote sensing is widely used in various spheres of human activity, such as surface monitoring, geodetic surveys, and agriculture. In addition to spectral research, remote sensing of the Earth uses other optical observation methods (such as LIDAR technology), radar and acoustic instruments. Unmanned aerial vehicles (UAVs) are used for regular monitoring. The advantage of unmanned launches is that they are significantly less expensive than manned flights. The main type of UAV currently used to solve a wide range of tasks is a quadrocopter. weight reduction is one of the important requirements in the development of wearable equipment for unmanned aerial vehicles. Another factor that determines the suitability of the instrument design for use in an aircraft is the structural rigidity and its resistance to vibrations arising from the operation of the engines. Minimizing the mass and increasing the rigidity and vibration resistance of the structure are two main requirements, in addition to ensuring the optical design requirements, which must be borne in mind when developing the design of a hyperspectral camera for installation on a quadcopter. The aim of this work is to develop a design for a hyperspectral camera. The design should provide the ability to install the system on a quadcopter.
