摘要:
A method is proposed for the determination of the modulation transfer function (MTF) of optical systems with symmetrical spread functions. In the image of a variable slit the central irradiance is measured and from that the MTF is calculated by means of a suggested formula on a desk calculator. A device, characterized by its simplicity, for MTF measurements of lenses is described and a test lens from SIRA with known MTF is evaluated.
