- Instrument Overview
The study of the imaging process in optical systems and the evaluation of image quality are key aspects of optical information processing. By characterizing the transmission performance of an optical system for targets at different spatial frequencies using spectral analysis methods and the optical transfer function of linear systems, it is possible to objectively and effectively analyze the information transmission performance of the entire optical system. Consequently, these methods are widely used in optical design and optical inspection.
