Abstract:

A method has been developed for generating amplitude masks with constant power spectra so that they can be used to measure the two-dimensional modulation-transfer functions of optical systems. This paper estimates the spectral stability of the masks obtained by the method developed here and of other forms of masks against the noise and geometrical distortions that arise when images of the masks are recorded by photosensor arrays. The possibilities of using them to measure two-dimensional modulation-transfer functions are analyzed. The two-dimensional modulation-transfer function of a digital camera is measured, using a mask obtained by the method developed here and correlation alignment of the rasters.
