-Instrument Introduction

The study of the imaging process and image quality evaluation of optical systems is an important aspect of optical information processing. Based on spectral analysis methods and linear system optical transfer functions, by characterizing the transfer performance of optical systems to targets at different spatial frequencies, the information transfer performance of the entire optical system can be objectively and effectively analyzed. Therefore, it is widely used in optical design and optical inspection.
