A Characterization of Low Luminance Static and Dynamic Modulation Transfer Function Curves for P-1, P-43, and P-53 Phosphors.

Abstract

A counterphase modulation technique is used to measure the static and dynamic modulation transfer functions for three phosphors of current interest to U.S. Army aviation helmet- mounted displays (P-i, P-43, and P-53). A family of modulation transfer curves, one for each temporal frequency, is presented for each phosphor. The measured MFT curves generally support the supposition that phosphor persistence is a critical parameter in the ability of a CRT display to accurately reproduce contrast modulation transfer in dynamic environments.
