Abstract: |
|||
| This invention relates to modulation transmission function meter used in optical modulation and its measurement method, wherein, the device is composed of computer, its LCD screen, rack, two-dimension color CCD and its base socket. The measurement principle is to use computer to generate random noise image as test input to get optical system MTF curve for only one test through analyzing images power spectrum intensity. | |||
