Description
In this project, techniques for the measurement of the Modulation Transfer Function (MTF) in large-dimension optical systems will be assessed to evaluate image-quality characteristics in telescope and CCD/CMOS cameras, focusing especially on Earth-observation systems. The evaluated techniques may be used to perform acceptance tests, verifications and calibrations of telescopes intended as payloads in space missions. This work proposes a signal processing pipeline to evaluate the MTF from data acquired in the experimental phase, for which simulated test images are generated to support the calibration of the pipeline. Furthermore, this work supports the definition of an experimental setup to be implemented in subsequent phases and the development of software tools for estimating optical performance in captured images in accordance with ISO 12233. The proposed processing pipeline for MTF estimation is presented in detail, along with a validation strategy based on an additional contrast measurement technique using sinusoidal Siemens star targets.
