Abstract

This paper study on a new scanning mini MTF automatic measure instrument and introduce the method of scanning the imagination point by grating and Fourier transformation to get the MTF, and designed a kind of MTF automatic measure instrument that could test the lens with caliber Φ<90mm, 28mm≤f≤250mm. This automatic measure instrument used CCD camera as the photoelectric detector, then use computer and its mightiness memory and processing function to realize auto test. This instrument is small and have high accuracy.
