| Abstract: | Modulation transfer function(MTF) is one of significant parameters for designing and evaluating an electro-optical imaging system.By proving the linear relation between an edge spread function and an inverse cumulative histogram of edge,an MTF measurement method based on statistical histogram is presented.Simulation and experiment including optics and detectors are designed.Physical experimental platform including an integrating sphere,target,collimator,digital camera and other devices is developed.Taking t... |
