MTF 측정에 의한 카메라 렌즈 해상력 검사 시스템 개발
Development of Measuring System for Camera Lens Resolution Based on the MTF Performance
초록
This System is developed for the estimation of the Camera Lens Resolution. Signal data proportional to light intensity is obtained and sampled from the 2D CCD. Based on the measured signal. the MTF charateristcs of a camera lens are measured. We could measure the sagittal and tangential MTF in the on and off-axis at the same time. The automatic measurig methods for optimal image plane, magnification, and best marginal direction of test lens are presented.
