MTF Full-Field Displays for Camera Lenses

摘要

Modern lenses offer high resolution and display a significant sensitivity to misalignment. Accurately detecting misalignment requires evaluation over the full field of view (FOV). We propose a method of utilizing commercial MTF test stations and custom software to measure, evaluate, and visualize the performance over this entire area. These techniques allow the detection and characterization of misaligned systems with greater accuracy than typical three or five field point MTF measurements.
