The resolution of on-board optical means of registration of aircraft under operating conditions depends on various factors. Very often a question arises about the assessment of the resolution of on-board optical means of registration of aircraft in conducting heterogeneous tests without having the necessary devices and devices in its arsenal. But before the testers there is no problem determining the quality of imaging or the requirements for on-board optical systems, and the task of how to simply and visually test or evaluate the resolution of on-board optical systems of aircraft. There are formulas, corresponding summary tables that allow you to make the necessary calculations to determine the specific values of these factors to achieve the specified parameters, however, for maximum convenience, a scheme - a layout (hereinafter - Measure) is proposed that allows determining the resolution of the installed photo and video equipment on aircraft by measuring the distance between two contrasting objects in Measure, where the camera begins to distinguish them as separate colors. Measurements are performed by analyzing the video (photo) of the image of the measure obtained from a certain distance. The visible part of Miri is analyzed, which distinguishes two contrasting colors. The resulting image is compared to its actual appearance, and thus the real resolution (the distance between the two visible segments) is determined. Thus, the Measure is intended for evaluation during testing of resolution of photo, video equipment (means of objective control) of aircraft. The considered technique will allow during the tests to move away from the theoretical part of calculations to assess the resolution of optical means of registration of aircraft. In addition, its production does not require significant material costs, and in the case of fabric or plastic film, it allows for its compact transportation and storage. The use of the proposed layout for the assessment of resolution will allow the test team, in the shortest possible time and with minimum equipment, to determine the compliance of the resolution of the optical means of registration of aircraft with the declared requirements in the conditions of flight experiments.References
