Abstract
An optical low-pass filter is indispensable for a single-vidicon color TV camera, in which a color-encoding dichroic filter is used, in order to eliminate the interference between luminance and chrominance signals. Properties of a rectangular-phase grating are described from the viewpoint of application of the color TV camera. The grating placed in the optical system acts as a one-dimensional optical low-pass filter, its optical transfer function (OTF) decreasing linearly as the frequency increases up to the cutoff frequency. The cutoff frequency and the dc level of the OTF are expressed as functions of grating parameters. The cutoff frequency is unaffected by varying the aperture stop of the optical system. It is shown that the trapezoidal-wave phase grating is also useful for the optical low-pass filter.
