Automated Analysis of Resolution and Contrast of Optical Systems

Abstract

The paper analyzes factors affecting the quality of optical systems during manufacture and operation. It has been determined that the quality of optical systems is determined not only by the technical characteristics of individual components, but also by a complex of factors covering design, production, assembly, and operation. Methodologies and techniques for analyzing the quality of optical systems are described. An algorithm has been developed and a software implementation of a system for evaluating the quality of optical systems has been performed using modulation transfer function (MTF) analysis with the sloping edge method, with the construction of heat maps and the detection of quality degradation in peripheral areas. It detects test targets in the image, analyzes their boundaries, and calculates key indicators such as MTF50, MTF10, and contrast. Experiments were conducted using a Canon EOS R8 camera with a Canon RF 15-30 mm lens in various configurations, and the effectiveness of the proposed method was tested. The image analysis showed the high quality of the optical system. The results obtained correspond to the physical limitations of the sensor and optics within the scope of the testing.
