Contrary to multifocal displays with fixed focal surfaces, the phase modulator shapes focal surfaces to conform to the scene geometry. A set of color images are produced and mapped onto a corresponding focal surface (Figure 4), with visual appearance being rendered by “tracing rays from the eye through the optics, and accumulating the color values for each focal surface.” Furthermore, Matsuda ''et al''. (2017) explain that their “algorithm sequentially solves for first the focal surfaces, given the target depth map, and then the color images—full joint optimization is left for future work. Focal surfaces are adapted by nonlinear least squares optimization, minimizing the distance between the nearest depicted surface and the scene geometry. The color images, paired with each surface, are determined by linear least squares methods.” <ref name=”5”></ref>

The focal surface display research team demonstrated that the technology depicts more accurate retinal blur, with lesser multiplexed images, with high resolution being maintained throughout the user’s accommodative range. <ref name=”5”></ref>
