The luminance range of cathode‐ray tube (CRT) systems is limited by glare associated with light diffusion in the thick glass faceplate. This is of particular concern in medical imaging applications, where images with wide luminance range and low contrast detail are displayed. To achieve the required display quality, careful control of the light transfort processes in the faceplate of CRTs is needed. In this paper, an optical Monte Carlo simulation code (DETECT‐II) for modeling the luminance spread in the CRT emissive structure is described. Using this approach, the effect of rough surfaces and anti‐reflective thin‐film coatings on luminance spread functions is examined
