Paper Abstract

The spatial frequency response of a CRT flying-spot-scanner system is discussed and film plane modulation response is calculated for response to periodic sine wave, square wave, and isolated Gaussian line signals on the input film. The effects of digital sampling on the spatial frequency response of a digital flying-spot-scanner are also derived from the digital sampling theory. The modulation response is then presented in terms of the film plane parameters for both analog and digital scanning systems and parametric trade-offs are discussed in terms of meeting performance requirements.
